I am trying to add 10% GST to my total column figure automatically

Perhaps one way to try ..

Click Insert Name Define
Enter in "Names in workbook:" box: GST
Enter in "Refers to:" box: =10%
Click OK

The above creates a named "constant": GST
that can then be used in formulas in any sheet in the book

For example, in say, Sheet1,
if you have the total for cols A & B in say, col C
i.e. in C2: =SUM(A2:B2), copied down

just change it in C2 to: =SUM(A2:B2)*(1+GST)
and copy down

This will compute the original total amount plus GST

And to update any future changes in the GST percent to apply everywhere
within the book, we just need to use the same route,
via: Insert Name Define
and change it there
