Chcuk,

Forget my lastr eply. The problem is as Keith pointed out.

mProduct = "" is Always True

That is how strings are compared in xBase. The strings are comapred one character at a time until the striong on the right is exhausted. Your string on the right has a length of 0 so it is equal to anything on the left.

Fix this by using the EMPTY() function instead.

IF EMPTY(mProduct)
