Custom Contact Form submit button stops working when style applied

I hope someone can help – I have put together a form using Custom Contact Form that works but now I want to style it beyond the default style. But as soon as I apply a style other than default the submit button stops becoming a button and just becomes dead text. The reset button remains a button.

I have deactivated and reinstalled the plugin but still it happens… please let me know what I might need to do to fix this – I am totally befuddled any assistance will be terrific.
