JavaScript Assistance

If you want to use Javascript, then first of all you need to stop the submit button from refreshing the page (by adding a 'return false' statement, I think).

Next, you need to give your dynamic elements identifiers so that Javascript can access them easily. For this:

<img src='" + part1 + part2 + part3a + "'>

Give it an id, say:

<img id='image1' src='" + part1 + part2 + part3a + "'>

And 'image2' for the other image.

Add the following to your readtext function:

document.images["image1"].src = part1 + part2 + part3a;
document.images["image2"].src = part1 + part2 + part3b;


This probably isn't fully cross-browser compatible, but at least it works on the latest versions of Firefox and IE.

And if you want to update the captions on the page, you'll have to do something similar:

"<b><span id='caption1'>" + part2 + '</span> - MACD </b><br>'

And use innerHTML or any equivalent function.

(By the way, you're passing this.form into readtext but not using it, so might as well eliminate the parameter.)
