Navigator and Firefox: Firefox and Navigator cannot render a common Javascript script?

Question

I wrote the following script;

function msOver(subName){
eval(subName). style. backgroundImage = url(imgs/download_bg.gif)';
}

function msOut(subName){
eval (subName) . style . backgroundImage = 'none';
}
