Where is your error happening? What line number?

Show quoteHide quoteSystem.Drawing.GraphicsUnit.Point,
System.Drawing.GraphicsUnit.Point,
System.Drawing.GraphicsUnit.Point,
System.Drawing.GraphicsUnit.Point,
Show quoteHide quote

in the save function where the dataset is returning null values

In that case you need to alter your SQL code and make it so that it doesn't
return null.  Or you can check values returned to make sure they are not
DBNull in your C# code.  That will fix it too.  It was a long time ago since
I did this so I don't remember how to do exactly. Search the net for DBNull
and I am sure that will get a lot of stuff.

I have some stuff on the site that might help you out.
