Problem with case stmt alternatives

Hi,

I posted my problem code on http://pastie.....

On lines 38-39 I have the code:
case colSymbol
when :Status || :Symbol || :TradeType || :Quantity || :Price

As colSymbol assumes various Symbols as values, only the first one
seems to match.
The || symbols don't seem to work in this context.

Any ideas why not?

Thanks in Advance,
Richard
