Alright, I'm having some really funky issue with this. I know it's a mismatch (obviously) and I want to know if the DevX community members can help me solve this issue. It's been annoying me a lot of late.

Code:
  try{
        libSQL myAddNewData = new libSQL();
        String strRownum =(String.valueOf(jComboBoxLName.getSelectedItem()));
        if (intChoice == 1){
            myAddNewData.AddNewData("INSERT INTO CUSDATA (FIRSTNAME, LASTNAME, PHONE, SIN) VALUES ('"+ strUserData[intCount][0] +"','" + strUserData[intCount][1] + "','"  + strUserData[intCount][5] + "','" + strUserData[intCount][8] + "')");
            myAddNewData.AddNewData("INSERT INTO CUSLOCATION (ADDRESS, CITY, [POSTAL CODE], COUNTRY, PROVINCE) VALUES ('" + strUserData[intCount][2] + "','" + strUserData[intCount][3] + "','" + strUserData[intCount][4] + "','" +strUserData[intCount][6] + "','" + strUserData[intCount][7] + "')");   
        }
        if (intChoice == 2){
            myAddNewData.AddNewData("UPDATE CUSDATA SET FIRSTNAME = '" + jTextFieldFName.getText() + "', PHONE = '" + jTextFieldPh.getText() + "', SIN = '" + jTextFieldSIN.getText() + "' WHERE ID = '" + strRownum + "'");
            myAddNewData.AddNewData("UPDATE CUSLOCATION SET ADDRESS='" +  jTextFieldAddr.getText() + "', CITY = '" + jTextFieldCity.getText() +"', [POSTAL CODE] = '" + jTextFieldPC.getText() + "'  WHERE ID = '" + strRownum + "'");
        }
        if (intChoice == 3){
            myAddNewData.AddNewData("DELETE FROM CUSDATA WHERE ID = '" + strRownum + "'");
            myAddNewData.AddNewData("DELETE CUSLOCATION WHERE ID = '" + strRownum + "'");
        }
    }catch(Exception e){
        jTextArea1.append("SQLException: " + e.getMessage());
    }
The error I get when I initiate the UPDATE command:
init:
deps-jar:
Compiling 1 source file to D:\devel\java\netbeans\Grade 12\SIN\build\classes
