My non-working PHP radio button checker

What I've been trying to do here is create a bit of php that will check one of 4 radio buttons if the value submitted in a text field on the previous page ($amount_front) is the same amount that the radio button is labelled as.

The value submitted on the previous page is a monetary amount, and the radio buttons are $10, $25, $50 and Other.

But if the user doesn't enter anything, I'd like it to select Other, but I'm not sure how I'd go about that either.

This code is before the <html> tag.
[php]
$amount_front = $_GET['amount_front'];

$ten = 'unchecked';
$twentyfive = 'unchecked';
$fifty = 'unchecked';
$other = 'unchecked';

if ($amount_front == '$10') {
$ten = 'checked';
}
else if ($amount_front == '10') {
$ten = 'checked';
}
else if ($amount_front == '$25') {
$twentyfive = 'checked';
}
else if ($amount_front == '25') {
$twentyfive = 'checked';
}
else if ($amount_front == '$50') {
$fifty = 'checked';
}
else if ($amount_front == '50') {
$fifty = 'checked';
}
[/php]

and this is the coding for each radio button (with their respective values)
[php]
<input name="amount" id="amount" type="radio" value="10" checked="<?php echo $ten; ?>" />
[/php]

(Yes I know I'm bad at php)

you need to add in the following at the end of your last if statement.

[PHP]
else{
$other = checked;
}
[/PHP]
