I created a custom group for our Performance and Goals module and wanted to know how would you check for an error that isn't as obvious as syntax.
(Job != "41" and Job != "764" and Job != "1976" and Job != "691" and ! Job != "4518" and Job != "4782"
The error is the extra ! in between and Job ! = "4518.
I was able to save the custom group and didn't realize this was error until a teammate checked.
