calculating notional values

["cwest" <cwest@xxxxxxxxxxxx>]

It's probably easy, or at least it should be easy, to calculate notional
values of futures contracts, but for whatever reasons I'm not finding it
so and would appreciate comments about any "rules" to do so. For
example, I thought that calculating the notional value of DX is last
price times 1000, and for GC it would be the same, but apparently not.
By the way, the Exchanges explanations aren't clear to me.

Thanks in advance
