Swapping text and images

[SipherDrakon]

I know I saw a similar posting about this but mine is a little more complicated and being barely able to understand javascript, i am having a little trouble.

<FORM ACTION="http://us.2.p9.webhosting.yahoo.com/forms?login=vansawardsplus" METHOD="post" NAME="Personalize" onsubmit="return ValidateForm();">
<INPUT TYPE="hidden" NAME="form" VALUE="contactpage">
<INPUT NAME="Subject" TYPE="hidden" SIZE=32 VALUE="Additional Information for 68CHSA">
<INPUT NAME="Personalize" TYPE="checkbox" VALUE="No"> No Personalization&nbsp; 
<p>
            <input type="hidden" name="on0" value="Style">
    <select name="Style" onchange="swap(this.options[selectedIndex].value)", "swapText('Product Description: 6X8 Gray Speckled Plaque. Plain Bordered plate 
        with a poem by Carol Huyser.')">
     <option value="">Select a Border
    <option value="images/68chsa2lrg.jpg" name="Designer Border">Designer Border
    <option value="images/68chsalrg.jpg" name="Plain Blue Border">Plain Blue Border
    </select><br>
    <input type="hidden" name="next_url" value="http://www.alwaysinmyheartinc.com/noform/68chsa.htm">
<p><i>Your Email Address:</i><font color=red>*&nbsp; </font>&nbsp;<INPUT NAME="Email_Address" TYPE="text" SIZE=20 VALUE="">&nbsp;&nbsp;
<input type="submit" value="Submit" name="Submitted_Successfully"><input type="reset" value="Reset" name="B2"></p>
</form>

Thats the form I am working with. But i am having trouble with swapping out text. At first I was told to put what I wanted changed into a span and then id it and use javascript to change it so here is my coding for that.

<script 
language="javascript">
function swapText(what) {
document.getElementById("myspanid").innerHTML=what; //this will change the HTML in myspanid to the HTML you specified when calling the function
}</script>

And lastly here is where i want my text to change. But it has to be done when an option is selected from the dropdown menu.

<span id="myspanid">Product Description: 6X8 Gray Speckled Plaque. Designer Bordered plate 
        with a poem by Carol Huyser.</span>

I can't figure out for the life of me why this code won't swap the text. Any help would be much appreciated.

<select name="Style" onchange="swap( this.options[selectedIndex].value)", "swapText('Prod uct Description: 6X8 Gray Speckled Plaque. Plain Bordered plate

Use the JavaScript console.

onchange="swap(this.options[this.selectedIndex].value)"

There was only ever one browser that needed that syntax and it wouldn't support your function, so you could use:

onchange="swap(this.value)"
