[SR-Users] append_branch with pseudo variables

[Carlos Ruiz Díaz]

I figured out what was happening.

By doing "$(branch(q)[1]) = "0.1";" I was trying to write into an non
existent branch since 1 is actually the second branch because the main
branch ($ru)  is not counted.

$(branch(q)[0]) = "0.1" // is the 1st.
$(branch(q)[1]) = "0.1" // is the 2nd.

Regards.

Carlos.
