<?php if (function_exists('contact_detail')) {
  	$chair = contact_detail('chair'),
		$address = contact_detail('address')	
		} 
	?>

line 2 has a comma at the end not a semicolon, line 3 lacks a semi-colon, the statement is thus incomplete, and will cause a fatal syntax error when it reaches the closing brace on line 4.

Also line 1 has both the opening tags and the if statement, line 4 is mis-indented, and line 5s closing php tag isn't aligned with the opening tag.

WP Coding standards would say you're also missing blank space between your function args and your parameters, and inside your if statement

What is wrong with line 1?

I can fix the indentations. :)

Its actually indented correctly on my machine, it just copied across weird.
