I've recently started using this template, http://joomla15.siteground.com/?template=siteground-j15-30, which has its search box at the top right hand corner of the template, along with a search button. My site (in rough form of course) can be seen here: www.frankalexanderdds.com/wam7682.

I've implemented the search box just fine (you have to hit enter to actually initiate the search), but I'm unsure of how to implement the search button.

I understand that it might involve some PHP code.

Would someone be able to give me some direction of what I need to add or where I should look to make this work?

I appreciate the help. Thanks!
