Add Clear and Loop Function to Macro Code

[SVTF]

Hello Pro's

This is for excel 2010

I am looking to either add a clear option and or a loop function to the follow macro code.
This code is working 100% however I need to add a clear option or a loop function when N/A is selected from the drown options in H

So as per the code below – When N/A-Must add comment is selected – Column I (same row) is prefilled with N/A - And the user would have entered something in Column J (same row) – Works as it should.
However there could be an instances when N/A-Must add comment could be changed to either No or Yes.

What can be added to the code below that if "N/A-Must add comment" is changed to either No or Yes…

•It will clear the data in Column I and J same row
•And then follow the rules in code for Yes and No
