Prepending Makes Duplicates

Prepending Makes Duplicates

Hello,

I want to prepend a Resource field in front of whatever the user typed into the Description. However, when I run my script (On Form Submit), it prepends multiple times, and I only want it to appear once.

This is my script:
var existing_description=$CS.getDescription();
$CS.setDescription($CS.getValue("RES_319_QUS_326")+"<BR>"+existing_description);

Please see the attached screenshot for the result.
I'm using SDP version 9.4 build 9400.
