Beats me. Really. Really strange. If you replace with 1/0 you get the same? I mean if an error occurs? Stef

Soâ¦ is that URL already percent encoded? If it isn't how do I specify what encoding should be used? ;-) Cheers Philippe

Let us know if we need to reintroduce it. But what would be nice is to understand exactly what was used and for what.
