I have a form that will be used to preview reports with the given combo box criteria. Everything was working perfectly with the first three combo boxes I made. The fourth one (which is blank in 264 of the 311 records) made the report only return 47 of the 311 records when I searched for all records (keeping all combo boxes blank). Is there a way to ensure that the total number of records are used in the filter? I hope my question is clear. (p.s. my OS is Windows XP) Thank you!
