I have a web page for programmed in I am getting an error when testing a form submitting data to an SQL Server 2008 database. I'm having issues finding the exact place where the error is occurring. I know the issue is a conversion problem, but I can't seem to understand the stack trace info to point me to the line or parameter or object causing this. This normally would not be an issue but I have over 79 parameters being fed to the database through a stored procedure. I am copying the error information below.

System.FormatException was caught
