I have the following yml file:

parameters:
- name: Schemes
  type: string
  default: 'Staging'
  values: ['QA', 'Staging']

- name: test
  displayName: Run Tests?
  type: boolean
  default: false

variables:
- name: variable1
  value: QA,Staging

trigger:
- master

pool:
  vmImage: ubuntu-latest

steps:
  - ${{ if eq(parameters.test, true) }}:
    # Loop Schemes parameter values..
    - ${{ each scheme in split(variables.variable1, ',')}}:
      - script: echo "Running tests.. ${{ scheme }}"

Current YML View:

What I would like to do?

I’d like to iterate through Schemes parameter values instead variable1 variable values.. How can I do it?
