I have a drop down list for the field Qb with a custom value list that only has the word "yes". My boss wants the field Qb to become empty for the current record every time he modifies the record. I tried writing a script to set the Qb field to blank and then used it on the script trigger onRecordCommit. But of course that means that every time we try to modify the Qb field, it will just go back to being empty. I am not very experienced in scripting. Is there anyway to make it so Qb won't become empty when we try to modify Qb but will go back to blank if we try to modify the other fields on the layout?
