I need to to enter a new value( the standard manufacturing thickness(SMT)) and divid it on /48 then check if the answer < 135 display (pass) if not display (Enter higher value) I tried if else statement but it doesn’t work
and also I want to display the (the standard manufacturing thickness(SMT=)) text input side by side with the MAOP(psi)= text input.
