This maybe a basic question, but I am new to programming.
I have two GUI forms running at one time, UploadGui and UploadPurchaseData. I need the UploadPurchaseData form to call a value from a text field in UploadGui called txtFirstName. UploadGui and UploadPurchaseData are separate jFrame files, but they are in the same project. 
Here is the code I have so far for the UploadPurchaseData button to upload the inserted values into the database
private void cmdAddPurchaseActionPerformed(java.awt.event.ActionEvent evt) {                                                      
    String ps = comboPurchaseStage.getSelectedItem().toString();
    int pv = Integer.parseInt(txtPropertyValue.getText());
    int la = Integer.parseInt(txtLoanAmount.getText());
    //here is where is need the code to reference txtFirstName from UploadGUI
}
Here is the code that opens UploadPurchaseData at the same time as UploadGUI is open:
private void comboLTActionPerformed(java.awt.event.ActionEvent evt) {                                        
    String lt = comboLT.getSelectedItem().toString();
    if (lt == "Purchase")
    {
    UploadPurchaseData anotherFrame = new  UploadPurchaseData();
    anotherFrame.pack();
    anotherFrame.setVisible(true);
    }
