Hi, Ramanan Kalirajan, thanks for the reply. I had solved my problem already without using any variables. Is there any weaknesses without using any variables? Because I find that most of the programmers will use variables to solve this kind of problem. Thanks again for your solution.Leave a comment:

Hi, Ramanan Kalirajan, thanks for the reply. I have two different equations and these two different equations is based on user input in which textfield. So I still have the problem about this. Besides, I am not really clear about the variables that you used (val, tgtEl).Leave a comment:

Hi, Dormilich, thanks for the reply. Ya, I know I should allow one of the textfield to be editable only, but in this case, the user is allowed to decide whether textfield B is going to fill or textfield C. So is there any other methods to solve this problem?Leave a comment:

Now I can choose my radio button. So now where do I need to place the statement for textbox to display the value of radio button. Because I put as below, the number display at the different textbox, not the textbox that corresponding with the radio button when I select the radio button. Thanks in advance.
...Code:function calcRadio(radio, val) { var arr = new Array(); arr = document.getElementsByName(radio);Leave a comment:

I had try this. But why it show in all textbox once a radio button was clicked? Moreover, it didn't calculate the value I expected. For example, for question 1, no matter what radio button (1,2,3,4,5) I clicked, it remains show value 1 in all the textbox. Why? Didn't the .value property will read the value for that radio button (for example, value 1,2,3,4,5) when it was checked and multiply with the number I write?
...Code:function calcRadio()
