JS: document.getElementById(var).style.display - Object needed error in IE8 only

I'm iterating through an array of strings (ids) and passing each element of the array to a function which either hides that element by id or shows it.

for(var tag = 0; tag < idtagArray.length; tag++){UpdateImage( idtagArray[tag], xmlhttp.responseText);}


    function UpdateImage( usediv, data )
    {
        if( data == null || data.length <= 0 ) {
            update_value.innerText = 0;
            return;
        }
     // [A5:1][A6:1][A7:1][A8:1]
        var start       = data.indexOf( "[" + usediv + ":" ) + 2 + usediv.length ;
        var end         = data.indexOf( "]", start );
        var data_value  = data.slice( start , end ) ;
     
     if( data_value > 0 )
     {
      document.getElementById(usediv).style.display = "";
     }
     else
     {
      document.getElementById(String(usediv)).style.display = "none";
     }
    }

The error is with getElementById - Object Needed. This only occurs on IE8; Mozilla and Chrome are fine. I even tried casting the parameter into a string with no success.

Can you provide an example of the values of 'usediv' and 'data' as passed to UpdateImage?

Yes, here is how i call the method:

var idtagArray = ["KT501-1_8","KT502-15_30","KT503-15_37","KT504-10_30","KT505-30_80","KT506-30_90","KT507-20_50","KT510-15_1440","KT512-0_1_2_3_4","KT513-30_80","KT514-0_1","KT520-0_1","KT525-0_1_2","KT526-0_1","KT527-0_9999","KT529-0_9999","KT531-0_9999","KT533-0_9999","KT535-0_250","KT536-0_9999","KT538-0_9999","KT548-0_1","KT549-0_1","KT550-102_120",
