Transfer data to another sheet

Hello all,

Great forum!

I joined to deal with a particular problem, I found the answer in another post which had a workbook attached.

I have tried to amend the workbook for my needs and have done so to a degree.
The problem I have is I am unable to get all the required data from the Invoice sheet onto the index sheet

I am no good with code! I have attached the sheet and would be very grateful for some help/advice

Thanks

Kevin
