Hello, I am currently trying to enable a button when administrator users role are logged in from perspective and disable a button when only regular users are logged in. I have attached the snapshot of the code! Can you please help me out with this issue? ![2023-07-25](https://us1.discourse-cdn.com/inductiveautomation/original/3X/2/2/22a8b3f8d4d87665f69ae15d2a0990f3149ae1f9.png) ---

You haven't explained what your issue is. I'll tell you one thing, though: `system.user.getRoles` returns a _List_ of roles, so comparing it directly to "Admin" won't work. ---

Apologies, I have created two roles with one being "Administrator" and the other being "User" And there's a spelling error - it is Administrator and not Admin The problem lies when the button is not enabled or disabled for the respective conditions when I try to login with Admin or User credentials ---

Where does this script live? Is it a custom method on the root container? ---

The script is written in the root container on startup ---

I think the issue is what Kevin had mentioned. You are trying to compare a list to a string. You could check if 'Administrator' is in the list of roles `if "Admin" in role:`. A simpler approach may be to use an expression binding directly on the enabled property of the button. `indexOf('Administrator',{session.props.auth.user.roles})>-1` might work correctly in the expression binding. ---

The expression binding should be: `indexOf({session.props.auth.user.roles}, 'Administrator')>-1`. I had switched the order of the parameters. ---

In expressions, `hasRole(role, username, usersource)` will also work (the second and third argument are required for Perspective): > [@Perspective: Error using hasRole(...) with only 1 argument](https://forum.inductiveautomation.com/t/perspective-error-using-hasrole-with-only-1-argument/26628/13): > > Why are you forcing the double quotes? The example only has double quotes to display that the value is a String. You'll need to get username and user source from the session props, here's a more specific example. I just included the other one because of the nice screenshot: > [@Perspective: Error using hasRole(...) with only 1 argument](https://forum.inductiveautomation.com/t/perspective-error-using-hasrole-with-only-1-argument/26628/15): > > I try to avoid double quotes if I can help it, but your original ‘shoulda worked’ works for me: hasRole('Operator', {session.props.auth.user.userName}, {session.props.auth.idp}) ---

To make it clear, you should _ **never** _ use the startup script to disable graphic components directly (not that you can). You should always use a binding on the component, or, in rare circumstances, a script from another graphical component in the same view. Consider the situation where you need to add other conditions to the enable button as well. If you use a startup script, you're screwed (so too are you using another component script without thinking, hence why I said that would be rare) ---
