I am trying to specify a controlsource. I basically just create a text field in a report, use the build tool to find the relevant field from a subreport/query, and then set it. I know the path is right for the control source because I am not typing it myself, I am selecting it.
The field I am referencing still exists and is actually located where the controlsource is pointing. But for some reason, I get this error. It doesn't make sense.
Can anyone please help?
