How to send an email with this form?

[greg]

Hello,
I have a calculation online form where the visitor put some data, click submit, and the calculations are displayed. I want to know how can I setup the form so I can get ALSO an email when the submit button is hitted?
Thank you for your help.

Here is part of the code:


[code]
this is at the beginning of the form:

<form name="estimator" action="<?php echo FILENAME_ESTIMATOR.'?pID='.(int)$HTTP_GET_VARS['pID'];?>" method="post" onsubmit="return checkForm(this);">

this is where the submit buttom is located:

<input value="Generate Estimate" name="submit" style="font-family: verdana; font-size: 8pt;" type="submit">
        <input value="Reset" name="reset" onclick="document.location = form.action;" style="font-family: verdana; font-size: 8pt;" type="button">
          <input value="Close" name="close" onclick="window.close();" style="font-family: verdana; font-size: 8pt;" type="button">
