Help On This Simple Script by Setag(op): 6:40pm On Aug 15, 2015

Function count() { var lbl; document.getElementById('lbl'); for (i=0; i<10; i++) { lbl.innnerHTML+= i+'<br>'; } }
the tags specifically:
<button type='button' onclick='count()'>start counting </button>
<div id='lbl'></div>

i keep getting this error on IE: unable to get property 'innerHTML' of undefined or null reference.
Kinda help fix this and explain..

You code will not run because you need to assign the object to the variable do this instead
var lbl = document.getElementById('lbl');

you did not assign value to lbl by mistake.. try indenting your codes too, bugs are, sometimes, easily fixed with proper indentation


function count() { 
         var lbl = document.getElementById('lbl'); 
         for (i=0; i<10; i++) { 
                   lbl.innnerHTML+= i+'<br>';
           }
 }


<button type='button' onclick='count()'>start counting </button>
<div id='lbl'></div>

sorry, the code is properly indented on the editor.
My mistake here, but on the real script, I initiated the var and assigned value to it.. I keep getting the same error.
I will check it out and get back.
