That looks as if the TxtBox.Value is of a type that is not numeric, probably character.

You can check the type of a TxtBox.Value with the type() or vartype() functions.

You can force the type to be numeric by explicitly initializing it, either in the Property Sheet (assign the value 0 to the .Value property), or in some Init() (in the TextBox itself, or in the Form).
