They are in the text box because you have it coded with the element id of "actualDays" inside an input field. What you need to do is instead use a div or p element and change the innerHTML. If you want it to be part of a line, and not stand on it's own, instead of the <div> use <span>.
<input name="actualDays" id="actualDays" value="" size="30" readonly="yes"/>
<div id="actualDays"> </div>
document.getElementById("actualDays").value= +days+" Day(s) "+hrs+" Hour(s) "+minutes+" Minute(s)";
document.getElementById("actualDays").innerHTML = days+" Day(s) "+hrs+" Hour(s) "+minutes+" Minute(s)";
I hope that helps. You can contact me through my website: www.dynamicdzine.com if you have other questions about this particular problem.
