got everything working perfectly in environment #1 (QA), using 2 variables
“Root” - path to web root
"ServiceName" - name of a windows service
I can see the variables in the snapshot for the release, and all variables exist for both environments. but when Promoting this release to the next environment, the variables don’t come through. I have also tried deploying the release directly to the 2nd environment but the same exists.
The only thing to note is that the variables for the second environment were added much later than the variables for environment #1
