"X" is reading the form value, but it is still passing and older "var thisMarket" value.

The objective is to take a zip code via HTML form:

<form id="market" name="market" onSubmit="return validateZIP(this.zip.value);" method="get" action="">
<input type="text" name="zip" id="zip" value="zipcode" onfocus="if(!this._haschanged){this.value=''};this._haschanged=true;" style="float:left; width:100px; margin-top:5px;">
<input type="image" style="float:left; margin-top:5px; border: 0pt none ; width: 22px; height:17px;" src="images/nav/bottom/linkbar/btn_search_btn.gif" onClick="findLda();">               
</form> 

The script being passed thru is:

function findLda(x){
    marketName = new Array();
    marketURL = new Array();
    zip = new Array();
    zip_temp = new Array();
    zipMatch = false;
    var shareZip = "Shared Zips";
    var thisMarket = "Market value";
    xmlDoc=loadXML("/_includes/market.xml");

var Offer,node;
document.getElementById('market').innerHTML='';
for(var j=0; j<xmlDoc.getElementsByTagName('market').length; j++){
    node = xmlDoc.getElementsByTagName('market')[j];
    marketName.push(node.childNodes[3].textContent);
    marketURL.push(node.childNodes[5].textContent);
    for(var k=0; k<node.getElementsByTagName('zip').length; k++){
        if(node.getElementsByTagName('zip')[k].textContent!=null){
        zip_temp.push(node.getElementsByTagName('zip')[k].textContent);     
        }
    }
    zip.push(zip_temp);
    zip_temp = new Array();
}

//loop the zip Array to find a match for the query Zip.
for(k=0; k<zip.length; k++){
    for(m=0; m<zip[k].length; m++){
        if(x == zip[k][m].toString()){
            zipMatch=true;
            thisMarket=marketName[k].toString();
        }
    }
}
alert(thisMarket);

}

The objective naturally is to take field input (A), pass it thru market.xml - initialize a loop and match a zip (B), alert the result (C).

Looking for any direction with what is existing or a completely new direction.

Thanks!
