Conditional Help - Noob Question


Could someone help me understand how i can do the following please?

I want a button to be disabled if data is null or when data is returned it is not a specific value.

But no matter what way I do it, i cannot get it to work

{{ !== "RESTORE" || === null}}}

Can i not use an OR || like this in Retool?

Try this:

{{ ! || !== "RESTORE"  }}
