URGENT...What is going on with my <asp:ListBox>?

Summary:
Say I have a page called issueReport.aspx page, i pass a URL that has fields Comments1, Comments2, and Comments3.  Comments2 is derived from selections from a limitless ListBox.   Then all data is passed to issueReportViewer.aspx which of, is the viewer for a CrystalReport.rpt...



Some More Info:  
So in more detail let's say I'm storing Comments2 in a field on the crystal report that is limited to 511 characters.  So I've truncated the string because I was getting an error:  Buffer too small for String or missing Null byte.  

(I would like to have added extra fields on the report but didn't know how to access new fields I added because it was a special field type in Crystal Reports called Report Comments and I guess you can only have one though you can add as many as you like...however I was unable to find a way to access them by their object name...only by (rpt  my CR document) rp.SummaryInfo.ReportComments...but couldn't find away to access ReportsComments2 as opposed to ReportComments1.)



The Problem:
To make a short story long, I couldn't find a way to add entire Comment2 string to CR so i truncated it as stated.  However, now the issue is if I select all 150 items in my ListBox since it's multiselect, and pass it to the page by QueryString, I get IE error:

Internet Explorer cannot display the webpage.   Most likely causes:You are not connected to the Internet. The website is encountering problems. There might be a typing error in the address.



Question:
Any thoughts?  Maybe some characters messing up querystring?  i don' t think querystrings have a limit to it's length.  Example queryString is below (Are / or () messing up querystring?):
