السلام عليكم ورحمة الله وبركاته
I have a multi record block and two list items and I want to populate the second list from two different record groups base on the chosen element in the first list

IF :blk_ctrl_2.lst_condition in ('GCS','SHOCK') then
populate_list('blk_ctrl_2.lst_opr', 'RG_NUMBER');

ELSE
populate_list('blk_ctrl_2.lst_opr', 'rg_text');

the problem I face is thaف when the user select GCS the rg_number group will be populated but when he tend to chose other elements for the next record the rg_text group will be populated for the whole item and the previos rg_number group will be replaced..which is wrong..
I hope I have explained my problem clearly so that I may get some replies from you..
هذا وجزاكم الله الخير وكل الخير

ممكن ترسل لنا المثال حتى نحاول حل المشكله والتطبيق عليه

Thank You Aziz for your replay..
I solved the problem by using LOV insted of using poplist Item.
and now I can populate the two record groups in one LOV each one at one time depending on the condition.
