Did you open a table, or create a cursor, with the desired alias, for your grid? For example:

* Form.Load()
create cursor GrdCursor (...)

By the way, you don't usually need a variable for an alias; the alias itself is a "variable" that points to a table or cursor. You can safely hardcode the alias name, without using a variable - and thus simplify your code a little.
