you have two extra double quote behind "checked"
<?php if($info['bringRefs'] ==1){ echo "checked";} ?>"
Remove them.
Hope it works...
<td style="width: 625px"><strong>I plan to bring a referee team to the tournament
</strong>YES:
<input name="bringRefs_ud" type="radio" value="1"
<?php if($info['bringRefs'] ==1){ echo "checked";} ?>
style="width: 20px; background-color: #81F7F3;">
NO:
<input name="bringRefs_ud" type="radio" value="2"
<?php if($info['bringRefs'] ==2){ echo "checked";} ?>
style="width: 20px; background-color: #81F7F3;"></td>
I tested following version with Firefox and IE7. Successfully
<?php
if(isset($_POST['bring'])){
$bring = $_POST['bring'];
}else{
$bring = '';
}
?>
<form method="post">
<td style="width: 625px"><strong>I plan to bring a referee team to the tournament
</strong>YES:
<input name="bring" type="radio" value="1"
<?php if($bring ==1){ echo "checked";} ?>
style="width: 20px; background-color: #81F7F3;">
NO:
<input name="bring" type="radio" value="2"
<?php if($bring ==2){ echo "checked";} ?>
style="width: 20px; background-color: #81F7F3;"></td>
<input type="submit">
</form>
