Contact Form 7 (code for send button)

Hello. Does anyone know how to do this:

It is probably pretty simple but I am not good with code.

The little red “send” button at the bottom of the contact form I am trying to change to my own send button.

This is the code for their default send button <p>[submit “Send”]</p>

This is the code for the one I made [maxbutton id=”9″]

Thanks.
