submit button(image field) spawns new window

[btish]

Hello guys,
I have a submit button in one of my forms that is spawning a new window every time I try and calculate my javascript function. The button is actually an image field that acts like a typical button, but again it spawns a new page.

I DON"T want it to spawn a new page. Any ideas on how to solve this?
The code is below:

<input type=&quot;image&quot; name=&quot;submit&quot; onClick=&quot;calculate()&quot; src=&quot;/roi_calculator/slices/images/input_interface_11.gif&quot; width=&quot;136&quot; height=&quot;35&quot;>

Thanks in advance for any help.

What is the goal of this button? You say to calculate your Jscript function but what does your function do? If there is no fix for this there might be a different way of doing it.
