I would like to use an option set that sets the color of a background based on the current user’s name.

For example, if we have a user named Adam, I would like the background color to be set dynamically using the first letter of his name ‘A’. If a user was named Bob, then it would set the background color based on the first letter ‘B’.

I have an option set that has 26 letters for the display (A through Z), and an attribute for Color for the HEX code. I am just not sure how to setup the dynamic color using an expression. I can extract the current user’s first name:trimmed 1:uppercase to get the letter, but I don’t know how to apply the correct color from the option set.

Can anyone point me in the right direction?

Hi there, @doug4… I just made a quick example, and this expression appears to do what you described.

Hope this helps.

Mike,

Thank you very much, this worked perfectly. I’m not sure how long it would have taken me to figure this out, but let’s just say I wasn’t too close.
