how to replace a variable in filters by indexing

how to replace a variable in filters by indexing

Hello,
I use Zenon 7.50
I have a screen of type faceplate, which has 3 containers that totally overlapp each other. One container has a screen of type standard, the other containers have screens of type Alarm Message List and Extended Trend respectively. I manage to have only one screen visible at each time by controlling the visibility attribute of the 3 containers via a variable.
I used a dummy variable (a structured variable which represents an object like a valve or a motor f.e.) to configure the screens for the faceplate and replace the dummy variable through {PARAM} by the switching function with real instances. Everything works fine for the container with the screen of type standard. But the screen of type AML needs a filter (of type Alarm Message List General) in oder to only show alarms from the currently selected structured variable.
I also used my dummy structure to configure that filter variable, but it does not get replaced.
Same problem with the Extended Trend General filter for the container with the screen of type extended Trend.
Any idea how to replace the variables inside those filters?
