enter image description hereI have a requirement, if a user chooses 'Copy' from a drop down an additional field needs content, and if the user choose 'No-Copy' then the additional field CAN be blank.

Here is my script and when it runs it works fine, but if 'No-copy' is selected afterwards the change does not happen in the list. So I believe its my script that is at fault.


any help would be great.


You need to set the formula value to TRUE in case user selects the "No-Copy". So, try using below formula:



  1. Sometimes comma(,) does not work in formula (I am not sure but it is based on something language on your site). So in that case use semicolon(;) instead of comma(,).

  • it works once as No-Copy, then as Copy, and then when I change It back again the column does not change on the list. – user3437628 Feb 22 at 14:34
  • I have added a picture where can see on the edit screen its one value and on the list its another. – user3437628 Feb 22 at 14:38
  • any ideas anyone ? – user3437628 Feb 22 at 14:52
  • even with the simplest validation it does not work - such as : =OR(TAtestColumnChoose="Copy",TAtestColumnChoose="No-Copy") – user3437628 Feb 22 at 15:25
