This has been discussed elsehwhere on this forum. You should probably search it for more info. Anyway, CR is supposed to use the local system data format, but it's buggy. They said they would release a service pack to fix it but I haven't checked if this is out or not. You should go to their site and see.
In my book I discuss making the parameter a string and using an edit mask of "00/00/00". Then use the CDate() function in your record selection formula.
