Hello All,
I keep getting this error -
Variable $dialog_id is set but never checked, most likely indicating an
error. If this was the intended behaviour, you may use the <trim> action to
reference the variable a second time..
The objective of using the $dialog_id is to increment it each time a new
call arrives.
I am not sure, how to use <trim> action in my script.
Please provide some example on using <trim> action in script.
I have attached my script above for your reference.
Thanks,
Anjana
