[Javascript] How many seelct items have been selected

[dev at qroute.net]

I wrote this function to cycle thro the options to find out how many
selected or checked.

function  GetOptionCount(obj,objType)


 var numchecked=0;
 var returnVal = ""
 for(var x = 0; x < obj.length; x++){
  if (objType=="select")
  {
   if(obj[x].selected)
   {
    //alert(obj[x].selected + '\n\n' + obj[x] + '\n\n' + x + 'value=' +
obj[x].value)
    numchecked++;
   }
  }
  else
  {
   if(obj[x].checked)
   {
    numchecked++;
   }
  }
 }
 return numchecked;
}


But it reports count 1 as the selected count in the following select  !...


<select name="Height_Feet" >
 <option value="" >Select your Height</option>
 <option value="137" > &nbsp;&nbsp;4'6 " (1m 37cm)</option>

 <option value="244" > &nbsp;&nbsp;8'0 " (2m 44cm)</option>
 <option value="247" > &nbsp;&nbsp;&gt; 8'0 " (2m 44cm)</option>
</select>


It reports the  <option value="" >Select your Height</option> as the
selected item.
Any clue what could be happening ?


Validation code is as follows;

Height_Feet = GetOptionCount(window.document.aboutme.Height_Feet,"select")
if (Height_Feet==0) { message = message + '\n' + 'Height [Feet] field is
left blank.' ;donotsubmit = true; if (firstculprit == "" ) {firstculprit =
'Height_Feet' ;firstculpritobject = "s"}}

Unfortunately, Height_Feet comes as 1 so although nothing is selected, my
function still reports one is already selected.
