Hi Jose,

I guess both the formula (the way you have used) are different ...

If(emailuser!="jose.fidalgo@coficab.com" || emailuser!="ricardo.almeida@coficab.com" || emailuser!="amelia.paulino@coficab.com" || emailuser!="cedric.soares@coficab.com" )

In the above example -

if emailuser = jose.fidalgo@coficab.com, then the condition emailuser!="ricardo.almeida@coficab.com" will be true and it will disable the control .. you might probably need && (and clause) to be sure that all the conditions are checked?

Hi Jose,

are you trying to disable the control for specific users?

Another approach might be to add your users to a new SharePoint group. Afterwards you place a rule on your control which is:

fn-DoesMemberExistInAudience(current user, your new groups name)

The inline function will check if the current user is in the group specified. If true you can disable/hide the control. The method is an inline function. Rules will only show you runtime functions so you will have to copy/write the function's name itself but they do work flawless in rules and also mobile apps so you should give it a try.

Kind regards,
Enrico
