Sorry, I didn't pay attention. The 'Return' is a bad name for the cursor. Try to use

crsResults instead for the cursor's name. Always try to avoid VFP words for your table names or field names or variables, etc.

>>m. is used to distinguish memory variables (m stands for memory) from the fields. It's not really needed, but in some cases when you have a field in a table named the same as a variable, you need to use m. to tell the program you meant memory variable and not a field (fields always have precedence).
