I have managed to produce this error after trying to set the focus of an
option button within a frame on a multipage form. It also says: "Unexpected
call to method or property access."

When I've had this error in the past, the only way I've found to fix it is
to start again with the form. In this case however I'm reluctant since it
would involve considerable work.

Does anyone have more info on this? The web appears to be devoid of relevant
info. A fix would be even better...

Cheers,

Matt
