shape border to red upon selection from drop down

[jw01]

Hello

I have expense data by county. I have managed to link the shape of county to a cell, so i can show the county name or $ amount in the shape itself.

the issue is, the map of county (shapes that make it up) cant contain the name of the county as the shape is too small, so it looks messy.

issue:
-i would like and having an issue with trying to make the outline of the shape go "red' when user selects a particular county (i have provided an example in the attached).

so basically, from my drop down list (cell C38), when i select a county, i want the outline of the shape for that county to have a "Red' border so user can visually see where it is located.

can someone pls help!

thx u
