Connection string issue?

I have a very simple form with a few textbox fields which inserts results into an Access2003 DB.

When I test on my local machine (before transferring to my host server) everything functions as it should.

But when I try it once I've transferred the files to my host server, the DB is not updated, but no errors are reported.

Is there something wrong with my connection string, or is it something else causing this?

Here are the two conenction strings - the first from my local machine, the next on the host server.

<connectionStrings><clear /><add name="CYCWorld2013ConnectionString" connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=&quot;C:\Users\Pretext Notebook\Desktop\cycworld1013\App_Data\CYCWorld2013.mdb&quot;"
      providerName="System.Data.OleDb" /></connectionStrings>

<connectionStrings><clear /><add name="CYCWorld2013ConnectionString" connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|App_Data|\CYCWorld2013.mdb;"
      providerName="System.Data.OleDb" /></connectionStrings>

Thanks,

Martin
