You give the reason yourself: product.case_qty is a numeric field. You can't use alltrim() - which is a string function - on a numeric value.

While an N(5) field stores it's numeric values in string format in the dbf file, it is converted to numeric (double) in memory, so your if found() else endif is setting HoldThisSAPCaseQty to a numeric value in the if case and the string "FNF" in the else case.

You would need STR(product.case_qty) to make HoldThisSAPCaseQty a string in both cases.

Bye, Olaf.

Hi Olaf,

I was only trying to convert it to a string because I was not sure how to get it embedded in:
strLbl = strLbl + "^FO25,65^BY.33^B3N,N,30,N,N^FD" + AllTrim(HoldThisSAPCaseQty) + AllTrim(label.cust_prod) + "^FS" + CRLF

What is the syntax for adding that field into the statement if I want to keep it numeric?


Olaf DoschkeSoftware DeveloperCommented:
You can't keep it numeric, as you want to add it into a string.
And Alltrim() does NOT convert to a string, it just trims a string, STR() converts to a string.

All I was already saying is you need to make this correction:

If Found()
   HoldThisSAPCaseQty = STR(product.case_qty)
   HoldThisSAPCaseQty = "FNF"

I hope this makes it clearer.

Bye, Olaf.

You have to convert it to the string otherwise you cannot embed it into the string.

Simply do what Olaf suggested or use TRANSFORM function:

HoldThisSAPCaseQty = TRANSFORM(product.case_qty)
