what is the actual value( lblMesg.Text) you are trying to pass ? If you trying to store the same in SQL then check whether the query string contains characters which are supported in SQL. IF there are some then you have remove them. If you still want to keep those then you have some sort of custom encoding and decoding of these values.

Try wrapping lblMesg.Text within Server.URLEncode function which should translate characters that are illegal in URLs..

For e.g change the relevant line as follows -

Line 1641:        Response.Redirect("EventEntryWizard.aspx?mesg=" + Server.URLEncode(lblMesg.Text), false);


See link below for URLEncode function reference -
