Best way to do a simple-ish calculation (sum two fields in a table, convert into a percentage)

Hey all,

I have two fields in a DB table, I want to sum those, then I want to divide one by the other and * by 100 to get the percentage.

I know you can do basic maths with the operator, but I can’t seem to get the above working where I first need to sum the field, and divide by the other sum’d field.

Any ideas how I can do this within Wappler?
