If-Then-ElseIf Simple Question

[Brandon Johnson]

This question is hard to explain so i will show you an example:

dim strng as string

Set find = CurrentDb.OpenRecordset("Name", dbOpenDynaset)
find.MoveFirst

If chkJob.value = -1 Then
If Len(strng) = 0 Then
strng = "find!title = " & cboJobtitle
Else
strng = strng & " AND find!title = " & cboJobtitle
End If
End If

If chkyears.value = -1 Then
If Len(strng) = 0 Then
strng = "find!yrs = " & txtYrs
Else
strng = strng & " AND find!yrs = " & txtYrs
End If
End If
..
..
..
Do Until find.EOF
If strng Then
ReDim Preserve names(x)
names(x) = find!id
x = x + 1
End If
loop


Im getting a data type runtime error#13 at the bottom where it trys to
do the "if strng then" within the loop. Does anyone have any
suggestions. it would help me out alot.
