MSBuild execution of Powershell Script file relative / absolute path

Question

I have a power shell script that I want to run with MSBuild. The script itself works and I can pass the path variables in with the command line; however, when I attempt to pass the variables in through MSbuild I get errors in the path.

 <?xml version="1.0" encoding="utf-8" ?>
 <Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
    <Import Project="C:\Program Files (x86)\MSBuild\PowershellTask\Powershell.targets"/>

   <Target Name="Minify">
   <PropertyGroup>
       <FilePath>\Scripts</FilePath>
       <OutputPath>\MinifiedJS</OutputPath>
   </PropertyGroup>
   <Exec Command= "powershell.exe -command &quot;&amp;.\MinifyCSS.ps1&apos;$(FilePath)&apos;&apos;$(OutputPath)&apos;}&quot;" />

How to I pass the path into MSBuild. The above code errors on /Scripts and /MinifiedJS. Here is the error:

powershell.exe -command "&{.\MinifyCSS.ps1'/Scripts''/MinifiedJS'}" The term '.\MinifyCSS.ps1/Scripts'/MinifiedJS' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again. At line:1 char:41 + &{.\MinifyCSS.ps1'/Scripts''/MinifiedJS' <<<< } + CategoryInfo : ObjectNotFound: (.\MinifyCSS.ps1/Scripts'/MinifiedJS:String) [], CommandNotFoundException + FullyQualifiedErrorId : CommandNotFoundException

I also tried place them in quotes and using .\ prior.

Any Suggestions?
