DataGrid using a table not a DataSet

[Leo]

Thanks for the Help in Advance!

I am a beginner in VB.Net. I am trying to create a form which is displayed in a email for our customers to fill in a Request for quote. I would like them to type data into fields and have it added to the Datagrid

I am constantly getting the error Column 'OALen' does not belong to table .

Any Ideas
