Would it be possible to make a Helper Row?
Since you want to increase row address by 10 for each formula you could do this:
In a sheet where you want to put formulas, in a (lets say first row) you place values:
Excel 2016 (Windows) 32 bit
<tbody>
[TD="align: center"]1[/TD]
[TD="align: right"]0[/TD]
[TD="align: right"]10[/TD]
[TD="align: right"]20[/TD]
[TD="align: right"]30[/TD]
[TD="align: right"]40[/TD]
[TD="align: right"]50[/TD]
[TD="align: right"]60[/TD]
[TD="align: right"]70[/TD]
[TD="align: right"]80[/TD]
[TD="align: right"]90[/TD]
[TD="align: right"]100[/TD]
[TD="align: right"]110[/TD]
[TD="align: right"]120[/TD]
[TD="align: right"]130[/TD]
</tbody>
Sheet2
You need to autofill this row until AO column
Then you could write this formula:
Excel 2016 (Windows) 32 bit
<tbody>
[TD="align: center"]49[/TD]
[TD="align: right"]3[/TD]
[TD="align: right"]9[/TD]
[TD="align: right"]0[/TD]
[TD="align: right"]0[/TD]
</tbody>
Sheet2
[TABLE="width: 85%"]
<tbody>[TR]
[TD]
Worksheet Formulas[TABLE="width: 100%"]
<tbody>[TR]
[TH]Cell[/TH]
[TH="align: left"]Formula[/TH]
[/TR]
[TR]
[TH]D49[/TH]
[TD="align: left"]=+SUM(
INDIRECT("fixture!L"&2+D$1&":M"&11+D$1))[/TD]
[/TR]
[TR]
[TH]E49[/TH]
[TD="align: left"]=+SUM(
INDIRECT("fixture!L"&2+E$1&":M"&11+E$1))[/TD]
[/TR]
[TR]
[TH]F49[/TH]
[TD="align: left"]=+SUM(
INDIRECT("fixture!L"&2+F$1&":M"&11+F$1))[/TD]
[/TR]
[TR]
[TH]G49[/TH]
[TD="align: left"]=+SUM(
INDIRECT("fixture!L"&2+G$1&":M"&11+G$1))[/TD]
[/TR]
</tbody>[/TABLE]
[/TD]
[/TR]
</tbody>[/TABLE]
and also autofill until AO column.
Note that row number is locked so if you copy cells from D49 to AO49 do next row formulas will adjust themselves.
P.s. Values in second table are random as I tested if formulas work.
