I don't think you're showing enough code for us to really be able to help you. I'm going to make a HUGE assumption since I see a single quote at the very end of your HTML. Is all of this HTML output a single string with your PHP variables referenced inside?

If that's the case, your syntax for referencing variables inside of quotes is incorrect.

$output = 'My name is: ' . $name;
$output = "My name is: " . $name;
$output = "My name is: {$name}";

If you're using single quotes, you must concatenate the variable. If you're using double quotes, you can either concatenate or wrap the variable inside of braces. There are more/other options when you include concepts like heredoc and nowdoc syntax.
 
If this doesn't help, you're probably going to need to show more code. It may help you to read over the manual page for strings since it references how to call variables.
