Insert row for specific range using if function

Hi everyone.

Im not sure if this is hard to do or not. I have attached a worksheet which shows my issue.

The situation
I have data in columns A through to D
Columns E and F are going to be comments which support the data in columns A to D in the same row. They are static data and will not be refreshed.

The issue
The data in columns A to D may be refreshed by new data being pasted in. If a new row is inserted during the data refresh this may cause the comment in column E and F to no longer correspond to the correct data in columns A to D.

I want to search the range in column A compared to column G (prob Vlookup) and if there is a new code in column A i.e. A3 in my worksheet i want to select the entire range of rows E and F from the row which doesn tmatch and move it down 1 row so it lines up again. In my workbook this would move the entire row E from E3 to end of the row and the same for F.

I hope i havent waffled too much. Thankyou so much for your help.
