I Can't Float The "More Details" Button To The Right

I used the [BUTTON] in place of the [CBUTTON], but it will not float to the right. I have tried every code I can think of in float to the rightCustom , but it will not CSS.

This is for the search page coupon layout. This is a test site that is being built. The url is
https://www.ehavasu.com/.

Any help to getting this done will be appreciated.

Thanks,

Tom
