Need a condition for custom field

Question

I'm trying to set up a condition or validation for a transition where a custom field (User Picker (single user)) user is in a group and not a particular user.  I'm not really familiar with scripting so don't understand the syntax too well.

CustomFieldValue("customfield_11407") = UsersInGroup("Prod-Support") AND not username=prod-support

This is what I tried, however, doesn't seem to work as expected. Note I did use a different group created just for this condition. Am I doing something wrong?

Looks promising, I'll have to test.

Thanks,

I would need to set this up without a plugin, I'm not clear on how to apply at least the first condition.

CustomFieldValue("customfield_11407") = UsersInGroup("Prod-Support")
