Hi Jim,

OK, i can create private variables, but i think i'll get the same result. It's a stupid situation that i really can't understantd. What i have is a PRG that holds information about the fields to each table (like descriptions, types, etc). I run them, when my application starts to check out if my tables are complete. Each time i read a PRG (for each table), i release those public arrays, and recreate them again. No problem! Everything is OK!
But, later, when i open a form, that will have a listbox with a description of fields, i must run the PRG again. New public arrays are created, and shouldn't get me any error. But, my listbox is empty, because that array is empty. It maintains (?) the size of the last time PRG was called, and all elements are blank!
But, i'll try to use you suggestion.

Thanks,

Ricardo
