Change color of button name on a main page

[Orgel]

I have a main page with buttons that you click on which are bookmarked to all the the other tabs.  So on the main page it is something like:

tab name 1

tab name 2

tab name 3

etc.

If you click on the names, it takes you to that tab.  Is there a way for the name to change color based on if any data is in the tab it links to.  For example, the table in tab name 1 may be blank because there is no data one day, but the next day it may be filled because there is data.  It is showing errors for a specific data set, so most days it should be blank.  So on days when the tab is blank, I would want the tab name  button on the main page to be green and if it has data, I would want it to be red.

HI @Orgel ,

Have you tried using the conditional formatting option for the bookmark navigation button?

I haven't tried this but how would you do it.

Group the bookmarks after adding them. Then insert page navigation button

Here's a blog post for that.
