I tried "expression" in the drop downs in button configuration but they seem to have no affect.

can you post more details what expression(s) have you tested and problems have you experienced?

this should work.

This is the most basic test I could think of. Simply showing or hiding a button based on the value of one, numeric property of the current item in a SharePoint list. I must be overlooking something simple…. I can hide the button on the form with the same simple expression (just testing for “!=” vs. “==” since the rule hides and the button config makes it visible). I could just use the rule, but that does not hide the ribbon function. The ribbon config doesn’t seem to work at all (unless I specify “No”, which does work).

Thanks,

use appearance expression like

fn-Equals(HideCancelButton,0)‍‍

== is javascript operator. it works in rules, calculation and other client side code since browsers can interpret it.

appearance expression is, however, server side evaluated (likely) by some nintex engine internally, so you have to use inline functions.

?That worked great! Simple solution... Thanks so much - I marked this as "correct answer" on Nintex Community.
