No ";" after the preceding "return"

so without the $hist=""; line what you have is:

if ($ptNum == "empty") return $hist = "empty appointment filled ". nowUS
() ." by " .$_SESSION['current_user'] . "\n";

In other words, the first $hist value after the return is only defined if
it's being returned from the function, because it comes between the if
($ptNum == "empty") and the next ";"

The // only creates comments to the end of line, it doesn't terminate the
return

So your if statement assigns the $hist value and immediately uses it as
the return value, when what you want is to assign the value if you didn't
return.
