The new formula randomsample() has a max of 4 parameters and you can specify the parameters inside the formula like this:
randomsample(sequence(1,100), 10, true(), false())
or you can use objects like so:
randomsample(TBList, TBCount, CBReplace, CBUpdate)
When using the the 2nd formula, all is fine, except for the 4th parameter - the formula keeps continuously updating regardless of the value of the 4th parameter.
