A little QueryDef Education Please?

I am getting an error when I try to requery a table and I do not see anything wrong with the code. Can anyone assist?

The error I get is:
Run Time Error '3421'
Data Type Conversion Error


Here's the code:

Public db As Database
Public rs_detail As Recordset

Private Sub Form_Load()
...
...
Set rs_detail = db.OpenRecordset("SELECT * FROM items ORDER BY blk_no ", dbOpenDynaset, dbReadWrite)
FindDetails (rs_master!blk_no)
...
...
End Sub

Private Sub FindDetails(findBlk As String)
Dim qdef As QueryDef
Dim strsql As String
strsql = "SELECT * FROM items WHERE blk_no = " & findBlk & " ORDER BY blk_no "

Set qdef = db.CreateQueryDef("", strsql)
qdef.SQL = strsql

****** The error occurs on the next line *******
rs_detail.Requery (qdef)



Thanks for the help!

strsql = "SELECT * FROM items WHERE blk_no = " & findBlk & " ORDER BY blk_no "

Shouldn't this read

strsql = "SELECT * FROM items WHERE blk_no = '" & findBlk & "' ORDER BY blk_no "

with the single quotes for the findBlk variable?

I have never used single quotes around the variable and it hasn't presented a problem in the past. That being aside even if I do something simple like:

strsql = "SELECT * FROM items"

Set qdef = db.CreateQueryDef("", strsql)
qdef.SQL = strsql

****** The "Data Type Conversion Error" error still occurs on the next line *******
rs_detail.Requery (qdef)

I have tried all types of combinations and no matter what I try I always get the same error

Have you tried using rs_detail.Requery (qdef.Name)?
