RE: [SMARTY] problem displaying float

Mark, et al,

I did some testing over the weekend and, as expected, can declare Smarty as
blameless, regarding my problem.

I've narrowed it down to the fact that my $fee variable is a simplexml
object. I now need to find a way of converting that to a float.
settype($fee, "float") doen't work.

Back to the PHP list.

Thanks for all suggestions.

Cheers

George
