Criteria syntax for Access

I am trying to use the DSUM function in Access. Here is the code as I currently have it.

Private Sub Command0_Click()
Dim rstUpdate As Recordset, dbs As Database
Dim intWeek As Integer, intTotal As Integer
Dim strLine As String
Set dbs = CurrentDb
Set rstUpdate = dbs.OpenRecordset("USED", dbOpenTable)
With rstUpdate
.MoveFirst
Do While Not .EOF
intWeek = !week
strLine = !Line
intTotal = DSum("[MIS]+[pty]", "USED", "[WEEK] = " & intWeek And "[LINE] = " & strLine)
.Edit
!totalused = intTotal
.Update
.MoveNext
Loop
End With
End Sub

When I run the program, I get a run-time error '13' and it states there is a type mismatch. It highlights the line of code using the DSUM function. I'm sure it is due to the code involving ("[LINE] = " & strLine) because it will work it I take it out. But I have to use the line as part of the criteria in order to get the info I need. Anyone know how it should be written?

Thanks,

Hi, is the strLine holding a textual value? If so, try changing this line:

Code:

---

intTotal = DSum("[MIS]+[pty]", "USED", "[WEEK] = " & intWeek And "[LINE] = " & strLine)

---

to this instead:

Code:

---

intTotal = DSum("[MIS]+[pty]", "USED", "[WEEK] = " & intWeek And "[LINE] = '" & strLine & "'")

---

Maybe you just forgot the quotes.

Just a suggestion, hope it works.

strLine does hold a text value. Unfortunately, the change in code still causes a type mismatch error.

I do appreciate your assistance.

Are you trying to get a sum from a text value? I thought you could only sum up numeric values (int, doubles, etc)

I'm trying to find out the total qty of MIS + PTY (TotalUsed) by Week/Line. MIS and PTY are number of boxes being shipped. There are several different types of boxes. Here is an example of the USED table.

Week Box Line Mis Pty TotalUsed
1 blue 1 FCO 2 5
1 blue 2 FCO 4 7
1 blue 1 FFR 5 10
1 blue 2 FFR 6 9

In the above example, if the program was running correctly, I would end up with 18 as the TotalUsed for the first and second records and 30 as the TotalUsed for the third and fourth records.

Hope this makes some sense.
