Need some help to add or modify query to add a new row

The query as is is shown below.

I have a win form (Form1) with the following:

A ComboBox1 where you can add new agentname.  A textbox named Associate_idTextBox that user will enter an 8 digit number that in the database is a string because sometimes the first number is 0.   A textbox named teamstatusTextBox (String VarChar(2)).  A textbox named franchisefeeTextBox that in database is decimal(3,2).  A textbox named splitTextBox that in database is decimal (3,2).

I am trying to modify the Query above to accept the values in the Combobox1 and the textboxes.

Thanks
