Remember I said you could hold the javascript  in a resource dll ... well
he's done just that.

Its perfect.

The code is in the ClientSideAdRotator ... internal class ClientScript

I am doing something with this lot at the moment and this is causing a
problem because there is another class called it somewhere else ( it won't
cause a problem  on its own).

When I have sorted it and isolated the code I'll post it ... but thank John
for it - its his code.
