VBA to copy multiple Text boxes values to a sheet

Dear Friends / Experts

I have a excel workbook & i want to do copy multiple text boxes (5,6,11,17,23,29,35,41,47,53,59,65,71) values to a sheet, but value should be copied based on combo boxes text to column E & text boxes value should be added in existing value ( for example if existing value is 10 & present value is 5 then column E value = 15)

Please see attached workbook for further details it's self explanatory.

Thanks in advance
