Thank you for that link, but the formula jsut brings me to a URL that doenst work instead of jumping to a section I need it to in the Interface Designer. Any thoughts? Maybe I am not following the formula right.
You need to replace the WqRri with the id of the record picker element in your interface page. You also need to replace the appid and interfaceid with the actual ids for your base and interface page. The formula field for the RECORD_ID() also does not take a parameter. See this thread for another example.
