Re: [SR-Users] append_branch with pseudo variables

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.
