1.)Java != Javascript so I moved that to the Javascript forum.
2.)When posting code please use code tags like the ones I just added for you there.
3.)What did you say is the problem with your code?

Hi,

Yeah sorry pretty unclear was just in a hurry.

I'm not sure what is wrong with the code, just when i push the button to calculate it comes up with the error: object required for the line

Expand|Select|Wrap|Line Numbers

 INPUT TYPE="button" NAME="button1" Value="Calculate" onClick="positive_gearing()"></td></tr><tr>

You're trying to access the form with the name "form".

Add this line to the beginning of your function:

Expand|Select|Wrap|Line Numbers

var form = document.forms.myForm;

Also you've spelt "positive" incorrectly (an i is missing).

Legacy code/browser compatibility

by: David Golightly | last post by:

This is just a quick poll for all you web devs out there: What browsers do you test on/are concerned about compatibility with? Obviously, you're going to test on current-generation browsers such as IE6, IE7, Firefox 1.5/2, Opera 8/9, Safari 2, etc. How old must a browser be before you stop worrying about it? Anybody here still test on IE4? Thanks,

For most users, this new feature is actually very convenient. If you want to control the update process,...
