can any one help me to correct my javascript

not going inside for loop when i have one checkbox in an row

[srins]

currently in my script,

function validate(error_message)
{
select_count=0;
alert("validate"+document.myform.TestCase.length);
for(index=0;index<document.myform.TestCase.length;index++)
{
alert("indexvalue"+index);
if (myform.TestCase[index].checked)
{
select_count=select_count+1;
alert("inside"+select_count);
}
}

if (select_count == 0)
{
alert("Please Select the particular TestCase then click" + ' '+ error_message+select_count);
return false;
}
else if (select_count >= 2)
{
alert("Please Select only one TestCase (not more than one)"+ "then click" + ' ' + error_message);
return false;
}
return true;
}

IF I have two testcases displayed in two rows,its working fine.But if i am having only one test case displayed in an row,i am getting an error

validate:undefined

and its showing as
"Please Select the particular TestCase then click" Edit 0);

Its not going inside the for loop ,when i have only one test case in row and showing validate:undefined ,
even if i am having one test case in an row.But if i have more than one testcases,its working fine.

can any one help me in this regard.

Thanks,
srins.

function validate(error_message) 
{ 
  var select_count = 0; 
  var numItems = 1; 
  if( document.myform.TestCase.length ) 
  { 
   numItems = document.myform.TestCase.length; 
  } 
  alert("validate"+numItems); 
  for(index=0;index<numItems;index++) 
  { 
   alert("indexvalue"+index); 
   var checked; 
   if( numItems > 1 ) 
   { 
     checked = myform.TestCase[index].checked; 
   } 
   else 
   { 
     checked = myform.TestCase.checked; 
   } 
    
   if( checked ) 
   { 
     select_count=select_count+1; 
     alert("inside"+select_count);
