Multiplier is throwing an exception if more than one line is entered...

When I hit submit, and there is more than 1 line in the multiplier section, it is giving me an error...
I have the debugger put in to get this.


Notice: Undefined index: purReq in /var/www/html/thelink/administrator/components/com_chronoforms5/chronoforms/actions/db_save/db_save.php on line 82

Figured this out...
