Hi All
I've Noticed that if i have a column on a grid that it's controlsource is an expression like "MyFunction(table.Field)", where Table.Field is a numeric type (MyFunction returns a character type). If i run my form i'll receive this error:
"Error loading file - record number xx. Grid or one of its members. ControlSource : Variable is not found"

My tricky to solve the problem was assign a minus before the parameter (with plus don't work):
"MyFunction(-table.Field)"

and i must treath the parameter correctly in MyFunction ....

AnyOne can explain me why ?? There is another way ? is a Bug ?

By all
