I’m trying to set a memory tag using the following expression on the system/client/RoleString which does not evaluate correctly.

The RoleString system tag is a list of strings, so I’m not sure how I would need to check the current users role against the system tag.

```auto
if ({[System]Client/User/RolesString} like 'Engineer', 1, 0)

```

I don’t believe this is working because ‘like’ isn’t a function in an expression. If I was use I would use the built in function [hasRole()](https://docs.inductiveautomation.com/display/DOC80/hasRole). From here you list the role your looking for, the user, and then the user source.

```auto
hasRole("Engineer", {[System]Client/User/Username},"user source")

```

If your looking at the current user and user source you should also be able to do just:

```auto
hasRole("Engineer")

```

It will return true if the user has the role and false if they don’t.

hasRole() worked perfect, thanks!

Clearing up a minor thing:  
`like` _is_ actually valid in the [expression language](https://docs.inductiveautomation.com/display/DOC80/Expression+Overview+and+Syntax#ExpressionOverviewandSyntax-Operators), but this is not the right use case for it; `like` would be used if you had a single string and wanted to check its content.
