Hello, 

I'm am struggling with a Vaildation Rule and really need some help! Please!  No syntax issues, it just doesn't work the way I need it to.
When I go to test the rule, if I select a from the picklist a single field System__c, "Axis360"), the rule fires and requires me to enter a value on 3 customer fields Device__c, Browser__c and Format_Reader__c. 

I'm not sure how to fix this. Hope this makes sense to someone.  Thanks in advance for any assistance
