Expressions for Visibility

I have made a screen for our 16 process vessels that use indirect tags. not all of the vessels have the same equipment so am hiding visibility through the expression “{Root Container.reactorNumber}!=14”. this works as expected but when i try to add other vessels to the expression it doesn’t work i.e. "{Root Container.reactorNumber}!=14, 9, 11. Does anyone have any insight as to what i am doing wrong?

This isn’t a valid expression. You’d have to use something like this:
{Root Container.reactorNumber} != 14 && {Root Container.reactorNumber} != 9 && {Root Container.reactorNumber} != 11
