Remove the duplicated var price declaration from inside the head expression

The previous repair re-inserted "var price = ..." at the point it replaced,
which landed between "var head = '...'" and its continuation. Semicolon
insertion then ended the head statement early, so the price and everything
after it fell out of the string and head rendered as a bare opening div.

var price is already declared above; the continuation line just needs to follow
the head assignment directly.
