fn-IsMemberOfGroup Inline Function Does Not Work With A Dynamic Group Name

Issue

The Nintex Form Inline Function 'fn-IsMemberOfGroup' does not work when the control has been configured to get the Group Name during the Nintex Form runtime. This means if you are passing a Control, Variable or something else as the GroupName.

Resolution

Use a static group when configuring the function.
Example: fn-IsMemberGroup('GroupName')
