If you take a look at the syntax highlighting colors, you'll notice line four is red instead of blue. This indicates a possible problem with your string delimiters (referring to quotes and single quotes). If you have a syntax highlighting PHP editor, it will probably show you similar results.
If you check out line 4, you'll see at the very end you have ."); Here you have the . and " but there's no more string. You can just drop the ." part.
Line 5 has similar issues. You have $newaura = ".$suguara." + 3 which doesn't make a lot of sense. You're attempting to take the result set (which is what $suguara is) and wrap periods around it, and then add 3 to the string. I'd recommend pulling this line out and look up the various mysql() commands needed to retrieve data from a result set.
