function mapGoogle(addyId) {


adVal = document.getElementById(addyId).value;


var gUrl = 'http://maps.google.com';


escapedAddy = escapeBlanks(adVal);


var loc = gUrl+'?q='+escapedAddy;


window.location = loc;


}


function escapeBlanks(adVal) {


eVal = '';


var last = adVal.length;


for (var i=0; i%26lt;last; i++) {


if (' ' == adVal.charAt(i)) {


eVal +='%20';


}


else {


eVal +=adVal.charAt(i);


}


}


return eVal;


}


%26lt;/script%26gt;


%26lt;/head%26gt;
