using param from an other "php snippet"

Hi,

I am calling 2 “php code” in a wordpres page.
I want to use the result of the the first one in the second one.
So I am trying to use (new from v1.1:
[php snippet=2 param="var1=val1&var2=val2"]
but val1 and val2 are coming from php variables from the [php snippet=1].
How can I build it ?
