Azure DevOps Pipeline - Use previously defined variables in variable definition

Question

I don't know if there's a way to use previously defined variables in variable definition. Basically I want to do something like this:

variables:
- name: basePath
  value: \\somepath
- name: servicePath
  value: $(basePath)\servicePath
- name: backupPath
  value: $(basePath)\backups

The later variables don't recognize basePath. Is there a different syntax I can use?

We do something similar, here's what we have in our yaml:

  - name: cdn-base
    value: 'https://cdn-name.azureedge.net'
  - name: 'CDN_URL'
    value: '$(cdn-base)/$(site-name)-$(environment)/'
  - name: NODE_MODULES_CACHE_FOLDER
    value: $(System.DefaultWorkingDirectory)/node_modules

Might just need to wrap your strings in quotes. Also check your agent type because it might be you using windows path separator on a linux agent.
