Hiding a panel if a column is one attribute or another

[ctoper11]

I know this must be a simple problem but I can't find it exactly on this forum or internet. I have a number of panels that are hidden when a choice column equals a number. Example below

not(contains(ApproverStage, "10"))

What I'm trying to do is set it so that if Approver Stage equals 10 OR it equals 11 that panel gets hidden. I've tried a number of ways using AND runtime function but I can't seem to get it. Any help would be greatly appreciated. Thank you in advance

(contains(Approver Stage, "10") || contains(Approver Stage, "11"))

OR(Approver Stage,"10"),OR(equals(Approver Stage,"11"))  

and(contains(Approver Stage, "10"), contains(Approver Stage, "11"))
