get cluster element when changed

Hello all,

Iam interested in knowning (after the user changes the value of a cluster) which element inside a cluster (any type of cluster) was changed.

so in an event structure case (clustername value change) i can get ctl ref, old val, new val.

On the other side I would like to get the either the refnum or name

I know old and new val will need to be variant (on my function) so that i can accomodate for any cluster. I have open G installed on my machine and have looked into the Open G LV data pallet as well as a Vcluster subpanel and havent been able to do this.

Here is an example of a given cluster

Here is another cluster example:

Method one:

Method two:

 Here is the skeleton of the function iam trying to build(testing the different possibilities):

So far I havent been successfull in this.

any help will be apreaciated.

regards,
