I am sorry to not offer a solution to your problem but one of the things I have practiced from the beginning of using VFP is to not use global variables! With a global you can have a difficult time finding out where a change occurs.

Sometimes I have seen developers create a global and change data types on the fly. Such a problem was discovered when an “End of Month” report was run. Gee, all was well for a month! And then…

Somewhere in the dark recesses of your program something is changing the value of your global variable. Change the variable name or go an extra step and get rid of all global variables!

(Easy for me to say!) :)
