I need to make the width of my button smaller

Hi,

Are you referring to the form http://www.jotform.us/form/61725185625156? I tried it in a simulator and looks fine. Please see below.

May I know the device you are using? Also, in your screenshot, the url is http://www.sbrselectric.com/ but when I accessed the page, there is no form embedded there. If the form is embedded to a page, please give us the url of the page as well.
