Domain Aggregate Function with AND Operator

[Derek Wittman]

Good morning
I've combed the help files and I'm still struggling with this. I'm trying to use a dmax function with an AND in the criteria (argument3). I can't tell if I am having trouble with the syntax or what. I get a RunTime Error #94, "Invalid Use of Null".

Here's the function call:
=WOCount([Forms]![frmRequest].[Divn],[Forms]![frmRequest].[Classe]

Here's my code
Public Function WOCount(di As String, cla As String) As Strin
Dim strcstr As Strin
strcstr = "division = divn AND classe = classe" ' I used the strcstr because I'd like to eventually convert WOCount into
'string with formatting of "00000" - another challenge I'm having is that the Excel TEXT function doesn't seem to work her
WOCount = DLast("[WOID]", "tblRequests", strcstr) +
End Functio

divn and classe are both textbox control values on my form. Ultimately, the WOID will look like this DD-C-WWWWW where DD is a division abbreviation (always 2 letters), C is the Classification left(classification,1) of Building, Electrical, Plumbing, Refrigeration, etc, and WWWWW is the text version of the Work Order

Can someone please help? Thank you very much in advance
Derek

Try Right("00000" & WOID,5)

Okay... I was able to get the first answer on my own. I

changed my thought process a bit based on what I really
needed (and not what I was hoping for). But the 2nd
question (the one about the converting to text formatting,
basically, I'd like leading zeroes for my number/text so
that 1 is 00001 and 1000 is 01000...) still stumps me.
Anyone?

Thank you in advance!

Thanks, Chris. I'm intrigued. I've never seen it quite like that. But after looking it over a few minutes, it makes sense.

I ended up trying Format(WOID,"00000") which worked. It seems that there is more than 1 way to develop a database - although some are better than others. I tend to do things the hard way

Thanks again

There's many ways to do everything. This is the way I've
used in the past, and its simple.

Good luck in your project.
