the document.all collection is an ie-only construct.  the closest thing to
it in mozilla is document.getElementById(), which ie5+ supports,

> eval('document.all.' + divName + '.innerHTML = "' +
> divValue + '";');

first of all, lose the eval() method.  its use makes your code very
difficult to write and read.  worse, it's a performance hog and will kill
the execution time on your script.  you can access properties of the all
collection using bracket notation, like this:

document.all[divName].innerHTML = divValue;

getting back to document.getElementById() though, this is how i'd alter your
function (assuming divName is an id being passed to the function and that id
only exists once in the document):

document.getElementById(divName).innerHTML = divValue;

hope this helps,
