Scheduling report in C# with parameters

Question

Hello. I'm going nuts here. I've written a custom web app that will serve as our new InfoView. My dev machine is Windows XP, I'm using Visual Studio 2005, ASP.Net 2.0 and Crystal SDK version XIR2. I have everything working properly with one exception....applying the parameters to the report when it's being scheduled. I have tried several different options that I've found online and in the Help files, but nothing seems to work properly. Absolutely any suggestions would be great! Here's what I've been trying/seeing.... First try - getting parameterFieldInformation from the reportViewer object - but the question here is, if I'm trying to schedule the report, how do I reapply the parameters to the InfoStore object for scheduling?  Second try - getting the parameter information from the InfoObject propertyBag - but when trying to add to the propertyBag the current/new values, it tells me that I can't add the Property "si_value1"    ex: io.ProcessingInfo.Properties["si_prompts"].Properties[x + 2].Properties["si_current_values"].Properties.Add("si_value" + (x + 1));         io.ProcessingInfo.Properties["si_prompts"].Properties[x + 2].Properties["si_current_values"].Properties["si_value" + (x + 1)].Properties.Add("si_max" + (x + 1), pdt.ToValue);         io.ProcessingInfo.Properties["si_prompts"].Properties[x + 2].Properties["si_current_values"].Properties["si_value" + (x + 1)].Properties.Add("si_min" + (x + 1), pdt.FromValue); Third Try - using the CrystalDecisions.Enterprise.Desktop.Report object to get the ReportParameters, however when trying to set the value of a range parameter, I keep getting the error message "One or more arguments are invalid." - I've tried setting the value to a ReportParameterRangeValue and a ReportParameterValue - both recieve the same error message - code is below and yes the e.FindControl does return the proper value entered by the user    ex: if (parm.ParameterName == "dt")                            {                                rval = parm.CreateRangeValue();                                TextBox txt1 = (TextBox)e.FindControl("txtRange1." + x.ToString());                                rval.FromValue.Value = txt1.Text.ToString();                                TextBox txt2 = (TextBox)e.FindControl("txtRange2." + x.ToString());                                rval.RangeValue.ToValue.Value = txt2.Text.ToString();                                parm.CurrentValues.Add(rval);                                                            }
