VBA in excel: EASY question for you

Here's my question, just scroll to the 'While Loop', and look at:

distance = Sheets("QMP-Auto").Range("C[range0]").Value

The C column has values from 0-1500, which i call 'distance'. I want to keep adding .01 to 't60auto' until 'distance' gets above 60, that way i can use the inital value of t60auto when distance > 60.

I think everything is fine until i get to Range, then it screws up... HELP!

Thanks!

Sub sixtyauto()

Dim dt
Dim rangeadd
Dim t60
Dim distance
Dim range0

dt = 0.01
rangeadd = 1
t60auto = 0
distance = 0
range0 = 3

While distance < 60
t60auto = t60auto + dt
distance = Sheets("QMP-Auto").Range("C[range0]").Value
range0 = range0 + 1
Wend

End Sub

Welcome to the Forums.

You have your variable enclosed in the double quotes so its evaluated as a string and not a variable.

Code:

---

distance = Sheets("QMP-Auto").Range("C[" & range0 & "]").Value

---

also, you should dim your variables as the needed type and not as Variants (no type specified will be dimmed as a Variant). Use Integer for range0 and Single for t60.

Holy crap that was fast. Thanks Rob! This place may become my new home for the next few months. :)

Still not working... Check it out again please. Thanks!!!! I'm slow, sorry about this...

Sub sixtyauto()

Dim dt As Single
Dim rangeadd As Integer
Dim t60auto As Single
Dim distance As Single
Dim range0 As Integer

dt = 0.01
rangeadd = 1
t60auto = 0
distance = 0
range0 = 3

While distance < 60
t60auto = t60auto + dt
distance = Sheets("QMP-Auto").Range("C['range0']").Value
range0 = range0 + 1
Wend

End Sub

Sorry for the delay, posting :D

You used single quotes instead of double quotes like I posted. The single quotes wrapped around with double quotes still makes vba look at it as a complete string and not a variable. ;)

While distance < 60
t60auto = t60auto + dt
distance = Sheets("QMP-Auto").Range("C[" & range0 & "]").Value
range0 = range0 + 1
Wend

THis still didn't work... =/ Any suggestions?

Did you change your Dim statements to include As Integer for range0?

Dim range0 As Integer

Yup heres my entire snip:

Sub sixtyauto()

Dim dt As Single
Dim rangeadd As Integer
Dim t60auto As Single
Dim distance As Single
Dim range0 As Integer

dt = 0.01
rangeadd = 1
t60auto = 0
distance = 0
range0 = 3

While distance < 60

distance = Sheets("QMP-Auto").Range("C[" & range0 & "]").Value
range0 = range0 + 1
t60auto = t60auto + dt
Wend

End Sub

Ok, looks like you have the range parameter incorrect.

Code:

---

distance = Workbooks(1).Sheets("Sheet1").Range("C" & range0).Value

---

Code:

---

Sub sixtyauto()

    Dim dt As Single
    Dim rangeadd As Integer
    Dim t60auto As Single
    Dim distance As Single
    Dim range0 As Integer
   
    dt = 0.01
    rangeadd = 1
    t60auto = 0
    distance = 0
    range0 = 3
   
    While distance < 60
        distance = Sheets("QMP-Auto").Range("C" & range0).Value
        range0 = range0 + 1
        t60auto = t60auto + dt
    Wend

End Sub

Mismatch Error on the Range line...

=/

Really? It ran fine for me in Excel 2003. What version are you running?

You could use a CStr conversion on the Integer variable to see f thats it.

Code:

---

distance = Sheets("QMP-Auto").Range("C" & CStr(range0)).Value

---

Excel 2002.... Kinda strange though, I didn't realize there was a 2002 till just now..

With the CStr version, i get a 'subscript out of range' error. Maybe it's my version??

You have it exactly aas I had posted in #9?

Where is the code located? Behind the sheet or in the ThisWorkbook class?

In a module...

Then you should reference the workbooks collection also in this line for better programming practice. Change the workbook to your workbooks name.

Code:

---

distance = Workbooks("Book1.xls").Sheets("QMP-Auto").Range("C" & range0).Value

---

Now to figure out why 2002 is acting different then 2003 lets try placing the entire range identifier into a variable instead.

Code:

---

Sub sixtyauto()

    Dim dt As Single
    Dim rangeadd As Integer
    Dim t60auto As Single
    Dim distance As Single
    Dim range0 As Integer
    Dim rangeTemp As String
    dt = 0.01
    rangeadd = 1
    t60auto = 0
    distance = 0
    range0 = 3
    rangeTemp = "C3"

    Do While distance < 60
        distance = Workbooks("Book1.xls").Sheets("QMP-Auto").Range(rangeTemp).Value
        If distance = 0 Then Exit Do
        range0 = range0 + 1
        rangeTemp = "C" & CStr(range0)
        t60auto = t60auto + dt
    Loop

End Sub

I just looked at it quickly, but might it have something to do with the source data? You have values being read into "distance" type single. Maybe your loop is hitting a string or reaching the end of the column and reading a null value? Both would kick out a mismatch I think.

Yes, thats true. Good spot mikey. I assumed that there would be integer type data in the cells.

here is how you should write it and should works fine

VB Code:

distance = Sheets("QMP-Auto").Range("C" & range0 & "").Value
