[Plugin: Contact Form 7] there's no send button on my contact form (using contact form 7)

There used to be a send button on my contact form page (using contact form 7) when I first had it. Then just recently people have informed me that there is no way to send us msgs. I looked and there is no send button on our contact us page. What happened? Can you tell us how to fix it? Thanks
