Running VFP 3.0b

I am creating an SQL Select statement that contains a UDF that passes the field name (the UDF essentially gets the first letter of each word in the field).

The problem is that this works correctly in Development mode, but in the exe I am getting the whole text from the field. And, it looks as though the function is not getting called at all.

i.e. SELECT GetLetter(PersonName) FROM .......

FUNCTION GetLetter()
PARAMETER jcField
..
..
RETURN lcResult
