I am able to create a simple query parameter to find entries with specific extensions, i.e. htm, lbi, jpg, js, etc. in fields with file paths. I have tried everything to create a single parameter to return multiple extensions. For example, htm and jpg only. One way I tried was to set up criteria for four separate extensions, i.e. [htm] or [jpg] or [lbi]. This brought up three parameters windows. If I select one or two and leave the third blank, it returns no results at all.  Ultimately, I want the parameter to apply to a report. If this is possible at all, I'm guessing it is going to take a truckload of VBA.  Ugh.
