Linking two separate iframes from two different webpages

I dont know how can I explain this. But I will try my best by putting entire issue in series of steps below.


Step 1: I have a web page with two <div> tags located besides each other. We will call them the right <div> and the left <div>

Step 2: Left <div> has a drop down list that dynamically generates navigation as shown in the code below.
<form style="margin-left:3%; margin-bottom:1%" action="" method="post">
<SELECT ONCHANGE="if (window.frames && window.frames.iframes) {
window.frames.iframes.location.href =
this.options[this.selectedIndex].value;
}">
<OPTION VALUE="Swimming.html">Swimming
<OPTION VALUE="TaxServices.html">Tax Services
<OPTION VALUE="TravelLeisure.html">Travel & Leisure
<OPTION VALUE="ymca.html">Waste Management
<OPTION VALUE="WaterManagement.html">Water Management
<OPTION VALUE="Welding.html">Welding
</SELECT>
<iframe id="theFrame" name="iframes" src="murrieta.html" align="top" style="margin-top:7%;height:95%; width:100%;"></iframe>
</form>

Step 3: To explain step 2 better, For e.g. if option "Swimming" is selected from the option group on left <div>, it will launch its child links in
in the iframe nam as "iframes"

Step 4: The option "Swimming" has an html file associated with it called "Swimming.html" This file has three links as mentioned below

<ul>
<li><a href="http://www.google.com" id="l14">about us</a></li>
<li><a href="murrietainfo2.html" id="l15">services</a></li>
<li><a href="murrietainfo3.html" id="l16">pricing</a></li>
<li><a href="murrietainfo4.html" id="l17">contacts</a></li>
</ul>

Step 5: To explain step 4 better, if "Swimming" option is selected, it will launch four links in iframe region

Step 6: NOW IT GETS REAL TRICKEY

Step 7: My Requirement is : say if user clicks "about us" link for "Swimming" option in left <div> tag, it should lauch "www.google.com" in
the iframe of right <div>. Say, if use selects "services" link for "Swimming" option in left <div> tag, it should launch "murrietainfo2.html"
in the iframe of right <div>


Step 8: i need to do this for all of options, as all of options in option list has child links that will be dropped in the left div iframe


PLEASE PLEASE HELP

Thanks,

Try to add target="rightframename" on the anchor (<a>) tag of "swimming.html" for about us.

Also, could you please provide a link to your page instead, this will speed up the issue.
