Lets say i have 3 text field here. I name the text fields with textfield a+textfield b+textfield c=textfield d.
If the result of the text field is equal to -1 or any negatif number, then the result appear in the text field d should be 0. But if it is a positive number, then let the aritmethic calculation count.
