Survey selection visual markers

[JPG963]

I am trying to create a clickable survey/grading form and would like to have a red circle encompass a cells contents when selected as pictured below. Any ideas on how to make this work? I will have approximately 10 questions, each with the below graphic following it.

would turning the cell with the 3 in it red suffice ?

Sure if it will turn red when clicked and stay red until another answer is clicked on within the line.

Select the cells of interest, apply this Conditional Format formula and set a fill colour

=AND(ROW()=CELL("row"),COLUMN()=CELL("col"))

Then right click the sheet tab, select View Code and paste in

Code:
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Application.ScreenUpdating = True
End Sub
