strange thing's happening to me.
I created a special page with the text field for a price. When I fill-in "0" (zero) in that field, I'm unable to output it. When I'm editing the page, I still can see that "0" is filled in, but when I try to output it, nothing appears (neither with get_special_field nor with return_special_field). When I add extra space or anything else, it's working fine.
It seems to me, that the system thinks that "0" means "nothing's filled", thus outputs nothing.
The problem is PHP's "feature" that null, "" (empty string) and "0" all evaluate to false.
In this case get_special_field will not output the field - but it will output the default value given in the second parameter.
So the solution to your problem is to use the default value, e.g. get_special_field('my_field_name', '0.00') or get_special_field('my_field_name', '<b>FREE!</b>').
