How to capture server control from Jscript and check if a control check box is selected

I have a gridview that contains check box in first column for each row.
I also have a check box outside the grid view called
>>>>
OnCheckedChanged="chkSelectAll_CheckedChanged" />
I either can select more than one checkboxes from gridview then click on a button to get the number of checkboxes selected OR I click on SelectAll checkbox ( which is outside the gridview ) which check all the checkboxes in the gridview and give me the number of checkedboxes. When I select inidividual checkboxes inside the gridview, th e count of number of checkboxes is correct ( displayed in a lable ) However;
When I click "SelectAll" check box, it give me total of all checkboxes chekced in the
gridview + 1 ( extra ) I am trying to get rid of this extra one by checking if this "Allcheckbox" is selected to so I subtract one from the total count .. like this

// java code ... code not shown does capture the total count into c variable
varAllChecked = document.getElementById('chkSelectAll');
if (varAllChecked.checked== true)
litCount.innerText = c - 1;
else
litCount.innerText = c;

this is not working any idea.
Thanks Bob

varAllChecked = document.getElementById('chkSelectAll');
var count=10;
if (varAllChecked.checked== true)
   {
         document.getElementById(" litCount").innerText=count+1;
}
else
{       document.getElementById(" litCount").innerText=count;   }
