Retrieving data in Matlab via LiveLink

Hi,

I'd like to retrieve some data from my Comsol Model via Matlab/LiveLink.
To be more specific:

I want to get the data of a displacement (u2) at the last timestep of my simulation (at 2.5 seconds) on the lower edge of a rectangle.

But how do I specify the lower edge?
I tried

mpheval(my_model, 'u2','t','25','selection','2')

in which '2' should be the selection number of the lower edge (at least this is number displayed, when I'm choosing the lower boundary for boundary conditions).

But that doesn't work.

Matlab claims that the selection with Tag 2 is unknown.

Please help me!

Best regards,
Simon
