Can anyone shed any light on the behavior of calculated fields in a multi-user situation, in general what happens when the calculation uses global fields to derive its result. And specifically when using an external function such as a range plugin in a calculated field which uses global fields to derive its result. I know that each user gets its own globals but what about the calcs that use them. Thanks in advance to FM Forums "The Best".

A calculation based on a global field will be unstored, so its value will essentially "change" for each user the same way a global field does.

One way to avoid this is to store global information in normal text or number fields in a related file. This way values remain the same for all users.
