Adding the values of two numerical columns together on RTF template
Hello
I am trying to add 2 numerical column values together.
I tried <?column_1 + column_2?> but it is abviously not that simple as I get an error when trying to do this
I tried <?sum(current-group()/column_1) + sum(current-group()/column_2)?> but that does not work either as it also returns an error
Any ideas how to add two numerical columns together in RTF template?
