Okay, that's a good resource, and a good start. But when testing
various values, I get the output :

value of x is:1
value of id is:222
value of id is:


where I would expect x and the second id to be 0, not blank. The test,
when it succeeds, displays 1, but when it fails, it displays nothing.
Test :

$testamt = $_POST["amount"];
$x = is_numeric($testamt);
echo "</br>";
echo "value of x is:";
echo $x;

$id = (int) $_POST["amount"];
echo "</br>";
echo "value of id is:";
echo $id;

$id = is_numeric($_POST["date"]);
echo "</br>";
echo "value of id is:";
echo $id;

Date is obviously not numeric, in that it contains the "/" character.

Any thoughts?

P.S. if you see something OBVIOUS, please be gentle, I'm a newbie!!!
