Help with SUMs in tables

[mhurford]

Hi,

I am trying to create an invoice template using word and need to add Sub totals to each table i have created.

Due to the constantly changing nature of the tables i do not want to keep having to remake the sub total tab so thought to create it as a separate table of its own beneath the contents table (see attached image)



is there any way i can have autosum add up all of the amounts in the table above or an easier way of doing this?

I am having trouble because the amount of columns and data i will have to add up is constantly changing so each time auto sum gets in the way when i have to add a new column unless i put it in a separate table altogether

Thanks for your help
