I am trying to use a table of users to determine if they can see profit - so we have a TRUE or FALSE against each user - i am then trying to use that to use Dynamic Zone Visibility to hide or show the profit graph in my dashboard -

I spent some time on this yesterday with one of the dev's at Tableau and need to rethink the approach - the boolean used as a trigger to show or hide the view has to be an absolute at the view level ( Huh? that is where the conversation started) - what is happening in your example is that this [Profit Visable]="TRUE" does return a TF but it is dependent on the user id (or email) -

as an example of what would be an absolute I added an email parameter and then this Fixed expression

this { FIXED : min( [Email]=[Email Parameter] and [Profit Visable] = "True")}

and it can be used as a boolean trigger (Note - it does not solve your problem - only an example of what works v what does not)

see the red tab

so is it possible to rethink the strategy on how to check against the Username? something else that will meet your need?

Thanks
