Hey All

I'm so new to Java and feel somewhat ignorant when it comes to code. this should be easy.
i have the fallowing code and am just trying to duplicate the fields. I have created the text and the test fields and the action button. but i'm just trying to duplicate and it only shows the two top jLabel's and jtextfields so when i browse to the html file i only c two labels and boxes. what am i dong wrong??

here is the code

The code to call the Applet

<HTML>

<HEAD>

<TITLE>Unit 5 IP Add</TITLE>

</HEAD>

<BODY>

Here is the output of my program:
<APPLET CODE="Add5.class"WIDTH="400" HEIGHT="100">

</APPLET>

</BODY>

</HTML>

First, in your HTML code, I see there is no space between the CODE and WIDTH. Change this:
<APPLET CODE="Add5.class"WIDTH="400" HEIGHT="100">
to:
<APPLET CODE="Add5.class" WIDTH="400" HEIGHT="100">

Next, under the init() method, you're setting the size of the applet to 800 x 600. But, in the HTML, you're setting the size to 400 x 100.  You might try playing with that to see if it fixes the problem.

I ran your code in Eclipse using its AppletViewer, and everything showed up fine, so I think your code is good otherwise.
