I'm building a report page that uses data from multiple Forms in my database, and I want to display calculated values using data from multiple Forms.

For example, the Attendance Form tracks the employee hours worked, but the New Build Form tracks employee productive time. I don't see an easy way to have a panel that displays the result of dividing the latter by the former.

It looks like it might be possible to do this via directly editing the underlying ZML in a panel, but it's not obvious what the syntax would look like. Am I missing documentation or guidance here?
