Hi Team,

I want to count the options chosen in multi-select custom field using script in jira.

if 2 options (Apple,Bat) is selected in multi-select custom field the count should be -2

I tried with the following code

"xMultiSelectVal.size()" --->output-9 //It is counting number of characters and special characters(,)
I want to count for number of options:- output--2
