Looking at some of the code you might need to debug a little but here’s some parts I see that are missing some syntax.
foreach( $repeater as $row ) needs foreach( $repeater as $row ) :
You are also missing the end of the foreach loop endforeach; ?>, which leads me to suggest you not render any HTML until you know the logic is working.
Strip it down and build piece by piece. Then post where you are getting stuck but pay close attn to getting the syntax buttoned up first before adding HTML.
