a problem with JavaScript?

I created this page with JavaScript
I get an error message when I open it.
There is no problem as far as I see, but the following message appears on the buttom

“Done, but with errors on page

Line 179
Char 3
Error ‘document.all.element6.style’ is null or not an object
code 0″

The line 179 is this
myObj = (document.all) ? eval(“document.all.element”+objNumber+”.style”) : eval(“document.getElementById(‘element”+objNumber+”‘).style”);
