Hi,
It would be easier to just upload an image of the tick and cross, then all you need to do is add the image tag in HTML as you would add a normal image.
Im assuming that this data is stored in a database and is a tick when $user_choice = 1 and a cross when $user_choice = 0.
($user_choice is the selected option of the user which is retrived from the database.
If this is the case then try this code..
<?php
If ($user_choice == '1')
{
?>
<IMG SRC="tick.gif">
<?php
}
else
{
?>
<IMG SRC="cross.gif">
<?php } ?>
You will have to make sure that tick.gif and cross.gif are uploaded to you site and also the paths are correct.
