I need value that user entered on the pipeline start to be used in the pipeline,
Pipeline is running on self-hosted windows agent and I need value to be used in PowerShell
My pipeline looks like this -
```
pipelines:
custom:
deploy:
- variables:
- name: myVar
- step:
runs-on:
- windows
- self.hosted
script:
- Write-Output "myVar = $env:myVar"
```
I enter `myValue` on pipeline run, but Write-Output displays `myVar = true` instead of `myVar = myValue`
If I use built-in variables, e.g. `Write-Output "myVar = $env:BITBUCKET_BUILD_NUMBER"` output is with correct value (`myVar = 22`)
So how can I get the value that user entered on pipeline start?
