Need direction: .setObject vs .setString and saving column info to database from GUI-Collection of common programming errors

My code has much repetition so i will just shorthand those parts. I do not know what is the problem with my code as no errors are reported.. just nothing happens.

I am using Netbeans GUI, jdbc and MS SQL. My connection is solid with preparedstatment = pst connection = conn etc.

My aim here is to save text and columns into a single resultset table in SQL.

The code is activated by private void in an action:

 private void INSERT1saveCustomers() {
    int index=1;
    int count = jTable1.getRowCount();

    for(int i=0;i
