Textfield calculation

Some body help me how to do a simple calculation. using java script

i have a 2 textfield,label and Button all DEFAULT GUI
textfield1 can only insert number
textfield2 also insert number only
and when i Press Button the calculation should be like this
textfield1 + textfield2 = label
and in the actual
4 + 5 =9

like textfield(int) + textfield2(int) = label (int) when press the button

i found the answer using int.parse :slight_smile:
