Jquery: How Do I set a value for an input field that is wrapped in td and span tag

Hi,

I want to set a value for any input field that is wrapped in a <td class="orderQty selected">

form:
<td><span><input/></span><span><Input THIS INPUT VALUE/></span></td>

the input field's value that I want to change is title="Order Number" with the value of the variable modTest
$('#Target').focus(function(event) {
  
 var mod = event.timeStamp;
 var modTest = mod / 1000;
  

}); 
});

I thought that I would have to search for a td with the class="orderQty" then get it's child that has the title="Order Number" ?

yeah the [ is supposed to be there it's the attribute matcher in jQuery
http://api.jquery.com/attribute-equals-selector/
SolutionabcAuthor Commented:
ok,

when I put that code in and do an alert with a value in the input box I get "Undefined"

for some reason it is not working.
$(document).ready(function(){
     
  $(".orderQty span INPUT").change(function(){
  
         if($(this).val() > 0 ) {
        
          $(this).parents("td").addClass("selected");
           var title1 = $("input [title = 'Order Number']").val();
            alert(title1);
        } else {
            $(this).parents("td").removeClass("selected");
        }
});

Sorry, slight problem with the matcher

This one gave me the value 0
alert($("[title=Order Number]").val());
