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

Code:

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:

Code:

var form = document.forms.myForm;

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