System.Data.Ole Db.OleDbExcepti on: Parameter ?_1 has no default value

[silesius]

I've been using VS 2003 to develop a webapplication using C#. Today I
exported the application to a remote webserver I begun experiencing
problems.
It's a simple application that retrieves some information from an Access
database. It worked fine when I ran on my computer. I use a parameterized
query to retrieve some customer specific information. Customer logs in, I
store the username they log in with in the session state and on the
following page use it in my parameterized query to retrieve customers info.
I'm using a data adapter with a dataset. Anyway, since I moved the
application to the remote server I started getting the following error after
logging in, but not all the time, sometimes it works fine. I'm relatively
new to ASP.NET and would appreciate it if someone could point me in the
right direction. TIA

Parameter ?_1 has no default value.
