VB with Sybase Access

[C-Nok]

I am working with VB on a project, that uses Sybase as the DB. In my project, I use the dataenvironment to access Sybase, I also used this to create a bound datagrid and some bound text fields. When I click on a record, on the grid it will also change the text boxes. My problem is this. I cannot make any changes to the fields without recieving the error.

Field not updatable, Bound property Name: Text, Field Name: Pin.

Is there somewhere I need to declare these fields as updatable?
Any help would be greatly appreciated.

Thanks,
Chuck
