adjust the color of submit button forms

HI,
I tried this as stated in de documentation
*—————————————-
// CSS – Contact form submit button
//————————————–*/

#top .avia_ajax_form input[type=’submit’] {
border: none;
background: #eb5424;
color: #f6f6f5;
}
#top .avia_ajax_form input[type=’submit’]:hover {
background: #000000;
}

but it did not change, even after clearing the cache.

I changed submit to the Dutch ‘Verzenden’ for the button, so I tried that wording in the CSS as well, but without success
Maybe ‘submit’ has to be something else,since I use the Dutch version of WordPress/Enfold?
