On Update Form Script Not Working On Multi Select

On Update Form Script Not Working On Multi Select

Hello Zoho Community!
      I'm having a bit of a problem. I've got a deluge script that runs on update in one of my form fields. At this point I'm just using the following script for testing. 

info 'Can you see me?!?';

If I edit a single record from a report and edit the appropriate field, I'll get my 'Can you see me?!?' prompt. But, if I select two or more records in my report and update them, I'll see no info box at all. Am I missing something here? I thought the code in the "on update" section should run regardless of who triggered the update.
