element with same name

if I have two forms on a page, both with a textarea I want to replace with a CKEditor instance and both textarea names are the same, will the editor work? it seems to replace just the first textarea field and leave a blank space where the second should be replaced.

any thoughts?

my current code to replace them consists of

if (CKEDITOR.env.isCompatible) {
    CKEDITOR.replaceAll(function(textarea, config)
        {
            config.toolbar = 'LimitedToolset';
        });
}
