    Angry Jtextfeild problems

    I am going nuts.
    Certain of my values in my jtext fields are not being passed off.

    I have 4 code segments like this:
    Code:
    private void jC2ImTextFeildActionPerformed(java.awt.event.ActionEvent evt) {                                                 
         String msg ="try  again";
            String  im2_input=jC2reEdTextFeild.getText();
              try{ 
              im2 = Double.parseDouble(im2_input);
              }catch(NumberFormatException e){JOptionPane.showMessageDialog(null,msg,"",JOptionPane.WARNING_MESSAGE);}
    The first one works(this gets both re and im); it is the second one that is giving me problems(re2 and im2) and the code format is the same for all four.
    The variables im,im2,re,and re2 are global .
    It is the method for Im2 that does not show up. The method for re2 is iffy.
    They get passed ro a calculation method say
    Code:
      private  calccomplex(ava.awt.event.ActionEvent evt)
      {
         Complex  c= new Complex(re,im);
          Complex c1=new Complex(re2,im2);
         // do complex math
      }
    Eveerything works great for univariate operations but as soon as I try do binary everoything
    go to hell !

    What can I do to make sure all re2 and im2 are passed off and don't get 0
    Help !

    }
    }

    values in my jtext fields are not being passed off.
    What does "passed off" mean?

    It means the values show up as not being
    0. I get 3 out of 4 being nonzero. Im2
    instantiates as 0 regardless what value is
    in the jeditfield.. .🤔😬

    Sorry, the small bits of code are not enough to show me the problem.
    Can you post a small, complete program that compiles, executes and shows the problem.
    Also include instructions on how to use the program to observe the problem.
