Simple code snippet

The following code results in a blank screen when mixed with the rest of my html. Is there something obviously wrong?

Thanks,

Jon

<?php

if ($amount = "" or $testcode = "") {

$amount=9700
$testcode="none"
echo($amount);
echo($testcode);

}
?>

The lack of semi-colons should've produced a parse error.

Try this:

<?php

if (!isset($amount)) {
$amount=9700;
echo $amount; }
if (!isset(testcode)) {
$testcode = "none";
echo $testcode; }
?>

What I would do in this exact case as long as you're trying to test to see if the variable exists...

<?php

if (!$amount or !$testcode) {

$amount = 9700; // need semicolon
$testcode = "none"; // need semicolon
echo($amount);
echo($testcode);

}; // should use semicolon
?>

Hope that helps.

Thanks! That did the trick.

The reason you got a blank page in this case is because of your if syntax. It should be

if ($amount == "" or $testcode == "")

notice the double equals signs.
