Disabling an input field when a radiobutton is checked
I want to disable an input field when a particular radiobutton is checked on the selection screen.
Whatever solutions I have tried (like loop at screen) etc., only disable the field after I press enter on the selection screen, also the modification done is parmanent. That is, after checking the said radibutton when I check any other radiobutton after that, the field still remains disabled.
Please let me know any solutions regarding this.
Thanks and regards
