I currently have three global Super Table fields, global.berkeleyDeliveryMatrix, global.oaklandDeliveryMatrix and global.sanFranciscoDeliveryMatrix, all of which have a plaintext column in them titled zipCode. 
The user has a profile address saved, which I'm looking to check against on the userZip field.
How could I search against all three of the global fields and return either a true or false statement if the set zip code was matched against any of the rows in the globals?
