Hi anyone,
I have a report with values in the "Last Name" column that links to another page (page 4) that opens when any last name in the said column is clicked on. However, before the last name link is clicked on its color is blue; but I want the link color to change to green after it is clicked on and the linked page opens; and I want the link to change to purple after the linked page is closed (visited link). Can someone provide a simple step by step example of how I can implement this in my app.

I tried looking at some posts that are similar but I am somewhat confused.

Thanks in anticipation for any assistance.
