DataGrid control error

I have two forms displaying  database records using a dataenvironment connection.  Form 1 has a datagrid to select which customer to display on the form 2.  Form 2 has many data aware controls to the same dataenvironment connection.  When a customer name is selected/clicked on the datagrid a button is pressed to display form 2.   The user can show form 1 again to select another customer name.  After selecting several different customers on the form 1 which changes the data displayed on form 2 the following error on the datagrid control displays when closing the form 2:  Cannot update '(expression)'; field not updateable.  

When this error displays the only action that has taken place is to change customers.

What is causing this error and what can I do to prevent it?

hi,

    When u come back to Form1 to add more customers UNLOAD the Form2 before showing1. After selecting customers LOAD the Form2 Again.

Remember : 'UNLOAD Form2'  not  'Form2.HIDE'

Hope this works.

BYE.

That seems to have worked. What was happening to cause the error. Also, will this have an effect on machine resources by loading and unloading the form multiple times?
