Parse Error in line 8. What am I missing? Thanks.

<?php

$length = 10.5;
$width = 20.5;

print ???the length is: $length
??

Thanks shaa. I’m taking an Intro to Programming class at the local community college and apparently I’m not taking good enough notes. I’m trying to pass between functions. I need my second function for the variable $Sales_tax to go into my first function and use variable $final_price, but don’t understand the scoping involved.
