i'm constructing a time from 2 text boxes on an aspx page and then trying to pass that time to a sql7 stored proc. i've tried a number of different ways of doing this, but always with the same result (Invalid index 3 for this SqlParameterCollection with Count=3). my guess is that i am just not understanding date/times in .NET. does anyone have any experience with this error or have a good source for more info?
