I have a question about the using of Excel and VBA.

Let’s say in cell A1 and A2, I input 1 and 2. Then I input formula
“=SUM(A1 A2)” into cell A3.

I would like to write a VBA code to have the following functionality:

Once I change the formula in A3, let’s say I input 4 to cell A3, the
color of the cell A3 should be changed.
Once I double click the changed cell A3, it should recover to the
formula “=SUM(A1 A2)”.

Anybody could help me out to solve the problem?

Thank you--

'This is worksheet event code, which means that it needs to be
'placed in the appropriate worksheet code module, not a standard
'code module. To do this, right-click on the sheet tab, select
'the View Code option from the menu, and paste the code in.--
