Count issues only if custom form is in use
I'm trying to create a report with a column that includes the number of issues on a project with a certain custom form attached. I figured the best place to start was with an IF statement that looks for a value in the custom form, but from there I'm a little stumped on to count/accumulate the returns. I also saw the "number of open issues" field, but I need to check closed issues for the form and count as well.
Does anyone have any advice how to do this?
