I need really help, I really angry now.
This Script is for the user only can type alphabet on that field.
As you see I use Persian Ascii Code it meanes the user can't type anything when his system language is EN and if he types anything in EN language he sees show custom dialog: change your system language.
everything is okay when he change his system language and type Persian, Farsi in that field but when he type a number in that field he must see show custom dialog: You van only type the alphabet here.
As you see I write another if and I said If ASCII code numbers show this custom dialog but when I write number I still see my first custom dialog
What is wrong here? how Can I fix this problem?
