How do I validate # > #

[Anon]

I have an auction that I am developing and I need to know how to validate that a # is bigger that the current #. For instance if an item is $100.00 I dont want someone to be able to bid $10.00. I need to make sure that the number that they entered is bigger that what is current. If you can help that would be great.

Well you just compare these two values like:

if($bid_current < $bid_original)
{
echo "error: You must place a higher bid!";
} else {
go on.....
