I have a report with a parameter that has the option to select all from the list. When I click the checkbox for "select all", all the boxes are selected, but then the page does a postback and some of the options are then deselected. I checked the data and everything seems ok yet for some reason I cannot "select" these particular options from my parameter list. Is the auto parameter window doing some kind of validation that will not allow me to select these particular choices from my parameter list? Thank you in advance for any assistance you can provide!
