For LOOP AT SCREEN

Hi experts,

I had developed a Selection screen with 4 BLOCKS. The first one contains 3 radiobuttons, when each of the radiobutton is selected, the appropriate BLOCK is displayed on the screen. This logic was written in LOOP AT SCREEN at the AT SELECTION SCREEN OUTPUT event. However i want a functionality now such tat e.g. second section is displayed, there is a check box inside the section, when that checkbox is checked, the select-option on that section should be in input = 1 mode.

Please let me know if you have any solution.

Thanks.

Warm regards,

Harshad.
