variable referencing problem (I think...)

menelaosmenelaos Posts: 45Member
I am trying to store a new entry in my database trough the form created on the webpage. The database fields under which the user-entered values are stored are the following:

//Add each of the values from the textboxes
r["Cust_ID"] = lbxcontacts.SelectedItem.Value;
r["Contact_Name"] = name.Text;
r["Contact_Position"] = position.Text;
r["Contact_Telephone"] = telephone.Text;
r["Contact_Fax"] = fax.Text;
r["Contact_Email"] = email.Text;

The Cust_ID value is read from a listbox. It doesn't seem to like my syntax though and keepsgiving server errors.
I'm not sure what i should do to fix it, but i believe it has to do with the referencing i'm doing between the Cust_ID field and the listbox selection.

I am attaching the code below.

If anyone can help, you'll be a life saver!

Cheers.

Menelaos Prokos.
