So I have a report that takes information from a query and displays it. The query has three fields so the report only displays three fields. Two of those fields are always filled in no matter what. One of the automatically input fields is a run number, so when they select the report I have it so that they have to input the run number parameter to display that record in the report.
The third field is often forgotten to be input by my coworkers. I do not want them to be able to open the report to print it out without the third field that they always forget to fill in having information on it. I would like for some sort of an error message to occur if the field is not filled in for that particular record. I am not sure if this is possible.
