Using a powershell script in a template

Question

I have a powershell script that I want to use in a template (edits a file). I want to store the script in the repo that houses the yaml template. I then want to call that template from another repo. Everything seems to work fine but it seems like the powershell script is not being pulled in when the build is triggered. I know there is probably some additional setup I need to do on my end.

This script alters a vdproj file. I want it to remain in the repo that contains the template as I want to be able to reuse that script from other repos that call in that template.

Error that I'm getting:

yaml template:

parameters:
  ArtifactPath: ''
  ArtifactName: ''
  ArtifactPublish: false
  Artifacts: []
  PublishClient: false
  Solution: '**/*.sln'

            targetPath: '$(Build.SourcesDirectory)/${{ artifact.ArtifactPath }}'
            artifactName: '${{ artifact.ArtifactName }}'

yaml that calls template:

trigger:
  - release
  - development
  - master
  - feature/*
  - task/*

resources:
  repositories:
    - repository: templates
      name: Project/RepoWithTemplate
      type: git
      ref: refs/heads/development

# This sets the BuildNumber variable
name: $(Date:yyyyMMdd).$(Rev:r)-$(SourceBranchName)
  
jobs:
- template: RW.Yaml.Templates/example.yml@templates
  parameters:
    Solution: '**/Example.sln'
    ArtifactPublish: true
    Artifacts:
    - ArtifactPath: 'Installers/ExampleInstaller/$(buildConfiguration)'
      ArtifactName: 'example'
      ${{ if eq(variables['Build.SourceBranchName'], 'development') }}:
        PublishClient: true

I figured this one out and now feel dumb. I just needed to check both repos out like below and it worked.

  - checkout: self
  - checkout: templates
