How to add landing page s-parameter to a form submission?

Question

Hi,
Really hoping somebody can help me. This is something I have seen used in many of my previouse roles and I would like to introduce it to my current position but am a bit lost. We develop our website inhouse and are currently in the process of migrating it to Dreamweaver CSS, which I am unfamiliar with.
What I want to do is introduce a tracking code that allows me to see excatly where the original click came from on all Email submissions (conversions).
What i would like to happen is, when a lead form from our website is submitted there is a hidden default field that comes through to us on the Email submission. That field should (if all goes to plan) pull the S parameter from the URL of the landing page. This S parameter is a code that I have generated and placed in the destination URL of all PPC ads and campaigns (as below)
I believe I have the correct piece of script ,  I’m just not sure how to place it and what I need to amend within it .
    <form action="jspostto.htm" method="get">
        <input type="hidden" id="hiddenParameterValue" name="hiddenParameterValue" />
        <input type="submit" value="Submit" />
    </form>
    blah<br />
    <script language="javascript" type="text/javascript">
        document.getElementById("hiddenParameterValue").value = getParam("f");       
    </script>
An example of the kind or code I am putting in is www.sapphiresystems.com/uk/sunsystems/index.htm?s=GUKAOOH02&K={keyword} in the destination URLs of PPC campaigns and Facebook links to the website as such www.sapphiresystems.com/sapb1/index.htm?s=FBSAPBOX.
Really appreciate any help or insight you can offer,
Many thanks
Kiti

Hi Both,
Apologies, yes we are on PHP,
This is what is really throwing me off .... i don't know what WEBBOT is? I have posted everything that was between form tags, just incase i let anything important out.
Again really appreciate all the help and advice,
Thanks , Kiti
