Hi there Bruce...
I may have left this message in the wrong place. It's just that the Wolfram website places a whole gallery of widgets that non-technical people like myself may place on their websites and the code shown to embed them in HTML just doesn't drive them.
Nigel, Wolfram has a lot of different websites. Which one do you mean - can you just paste a URL link in the post?
Is this about CDF Plug-in, Wolfram|Alpha, Cloud-deployed app, or something else?
