Question: I must be doing something differently than what was asked and answered here because the solution does not appear to be working for me: [TeamCity, passing an id generated in one build step to a later build step](https://stackoverflow.com/questions/8219493/teamcity-passing-an-id-generated-in-one-build-step-to-a-later-build-step)

I want use a string generated by one build step in a final build step. So far I have set up an environmental variable called "TEST" that is empty. Both build steps use the Command Line Runner.

Build Step #1:

```
\##teamcity[setParameter name='env.TEST' value='test']

```

Build Step #2:

```
echo $TEST

echo %env.TEST%;

```

Placeholder for now, but if I could access the test string ('test') set in Build Step 1 I would be so happy.

Answer: 
I think you have an extra "\" in there. Try removing that and add double quotes around it and it should work. 

```
 "##teamcity[setParameter name='env.TEST' value='test']"

```

If it doesn't work try using Powershell runner type as I'm using that for setting it and it works.
[Here is official ticket](https://teamcity-support.jetbrains.com/hc/en-us/requests/1031952) about addition double quotes and echo (Write-Host - OS dependency).
