Multi forms on a single web page??

[wxdqz]

I am attempting to use multiple forms on one web page. Eash form has a unique form name. I amnot sure how to use javascript to validate the different form(s).
Example of form tags:
<form name="formName1" method="POST" action="http://somethinghere.cgi" onSubmit="return checkForm(this.form)">>
<input...>
<input...>
<input TYPE="submit" NAME="submit" VALUE=http://www.webdeveloper.com/forum/archive/index.php/"Submit">
</form>

<form name="formName2" method="POST" action="http://somethinghere.cgi" onSubmit="return checkForm(this.form)">>
<input...>
<input...>
<input TYPE="submit" NAME="submit" VALUE="Submit">
</form>

<form name="formName3" method="POST" action="http://somethinghere.cgi" onSubmit="return checkForm(this.form)">>
<input...>
<input...>
<input TYPE="submit" NAME="submit" VALUE="Submit">
</form>

Thanks in advance for any help!
