Cant drag formula down column

[help needed yes please]

I am not much good at this and any help would be appreciated.
I can’t drag formula down column.
=Sum($E59:E164)/105
=Sum($E59:E165)/106 Note division is Ascending by each entry
Drag gives: =Sum($E59:E164)/105
=Sum($E59:E165)/106 which is correct
=Sum($E59:E166)/105 XXXXXX
=Sum($E59:E167)/104 XXXXXX
Dragged entries reduce the division with leach new entry
Any advice?

I cant see a 'Browse' option ...

Perhaps you are looking in the wrong place:
File -> Options -> Add-Ins -> Down the bottom .. Manage 'Excel Add-Ins' -> Go
If the Mrexcelhtmlmaker20170807 does show up there, then 'Browse' to find it.
