I have a report that I'm running off a query with date parameters (Start date, End Date). The query runs fine, but when I run the report it gives me a "too complex" message. I'm sure you are familar. Here is the kicker, it will run fine until I put the date parameter more than 13 days. Then it gives me the error. Does not make any sense. Any ideas. I use >= [Start Date] And <= [End Date] in the query. I ahve done this on several other reports. None have given me this errror message when I run the report. I kind of a novice so I hope I'm explaining this correctly. Any help would be apreciated. Thanks!
