Using ASP.NET with an access DB - (I didnt pick the database!!)

I have a formview1 on my page with databound textboxes... All I need to know is how in gods name do I update my records?? It seems when I attempt to use the following:

dsLeads.UpdateCommand = "UPDATE MYtable SET MyColumn = '" & txtFirstName.Text & "' WHERE ID = txtID.Text

I get an error?? Why cant I find the value of txtFirstName.Text from a Fromview??

PLEASE SOMEONE HELP!
