how to show / hide keyfigures

Hi,

i need to show/ hide different key figures (measures) in my data source based on the selection in a list box. i checked the ipad example (template3) which contains an example on restriction on measures. in my case it does not work. How do i know the name of my key figures dimension .

in the Example its stated like this:

DS_1.setFilterExt("Keyfigures", LST_MEASURES.getSelectedValue());

--> the syntax checker is complaining about "Keyfigures" ? how do i find the name in the Query / DS i embedded.

Tahnk you
