HI experts,
I created a screen 101 with three i/o fields A, B, C.
Created a push button that will subtract A and B and display result in C.
Now i want to display an error message if the user enters lower value for A and higher value for B.
Is there any command like at screen 101?
I think i can not use at selelction-screen as it is screen 101.
Plz show me a way to dela with this.
Thanks in advance.
