I am using DSum as a default value on a form but am not getting the correct result.  Probably because I have " and ' marks wrong.  Can someone help?  Here my code:

=DSum("Qty","tblProdInventory","'Style = #10 Product' & 'CompanyName = frmProjectDetail!txtCompany'")

Sorry, posted too quickly:

Also, understand that a Default value ONLY impacts New records. It will have absolutely no impact on Existing records.

And, in your case, if there is no value in txtCompany, or if txtCompany is on the same Form where you're running this, then you will almost certainly run into issues with it.

Try this one

=DSum("[Qty]","tblProdInventory","[Style] = '#10 Product' And  [CompanyName] =' " & Forms!frmProjectDetail!txtCompany & "'")

Sincerely,

No leading space:

=DSum("Qty","tblProdInventory","Style = '#10 Product' And CompanyName = '" & frmProjectDetail!txtCompany & "'")

<Tried that one and now I get no result in the field.>

Are you absolutely sure that your DSum will return a value? That is, are you sure this is at least one positive value in the Qty field for the Criteria you've entered? That is, there is at least one value in that field where your Style is "#10 Product" and the CompanyName is the value in Forms("frmProjectDetail").txtCompany?

Does the CompanyName contain any odd names, like O'Brian? If so, you'll need to "escape" those:

=DSum("Qty","tblProdInventory","Style = '#10 Product' AND CompanyName ='" &  Replace(Forms("frmProjectDetail").txtCompany, "'", "''") & "'")
