Hi John

If JobNumber is text, you need to wrap the value in single quotes.
Also, if your textbox may be Null, and DefaultValue should be a String.
Thus, try this:

= "'" & Nz(DMax("[ItemNumber]", "tblJobDetail", "[JobNumber] = '" & [Forms]![frmProject]![txtJobNumber] & "'"), 0) + 1 & "'"

This must be something I'm simply not seeing. Why doesn't this work as the
default value for a textbox on a popup form?
 
= (DMax("[ItemNumber]", "tblJobDetail", "[JobNumber] = " &
[Forms]![frmProject]![txtJobNumber])) + 1
 
ItemNumber is Integer
JobNumber is Text
 
TIA
 John B.
