Number checking?

[Anon]

I have an error checking that checks number amounts. If they don't equal each other it gives an error.
95% of the time it works. When it doesn't I print out both values on the page so I could see what they are. They are identical but PHP says they don't equal and gives an error no matter what you put in.
Does PHP have a glitch in number checking?
Any ideas would be appreciated.

Below is the code.

echo "$amounttot<br>";
echo "$decamount";

if ($numbcheck != "skip")
   { if ($amounttot == "$decamount")
			{echo "good";}
	else
	        {$err .= "<tr><td colspan = 3><font color = red size = 3>Your individual restitution amounts do not add up to the total.</font></td></tr>";
		   $go = "no";}

Get rid of the "
in:
if ($amounttot == "$decamount")

Just because it looks the same on screen, doesn't mean that the values are necessarily the same. You may want to use the trim() function around the variables to get rid of excess whitespace or special characters that might be interfering. Check php.net for more details.
