You'll need to make sure your report name is formula rich-text, and then something like this will work:
var bool overdue = (Today() - [Last Opened Date]) > Days(120);
var text name = [Field that actually has the report name]; //This is the text that will show in your element
"<p style='text-align:center; width: 100px; " & if( $overdue, "background: red; color:white;"'>" & $name & "</p>"
The <p> tag just make it a block element so you can set a standard width to make the column look the same width up and down, adjust as needed. In the above I just have it setting the background to red and font-color to white, you can plug in your own hex color or alternate color though as needed.
Thank you Chayce. Do you know if I can change my Report Name field from text to a formula rich-text field without losing the data?
If [Report Name] is a text entry field, and not already formulaic then no, you do not want to change it given that all of the data will be lost.
If it is an entry field - then you would want a 'new' field that is formula rich text, and you will just display the value of [Report Name] instead and you would swap out to using the rich-text field on reports potentially so it showed with the style you're looking for.
Thank you so much Chayce!
