Proper puppet variable declaration

The problem:

Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Syntax error at ','; expected '}' 

Wrong variable declaration:

class repos::params {
      $baseurl = "foo",
      $baseurl_key = "ha",
      $sles12_baseurl = "doo",
      $sles12_SDK_baseurl = "ken",
}


Proper variable declaration:

class repos::params {
      $baseurl = "foo"
      $baseurl_key = "ha"
      $sles12_baseurl = "doo"
      $sles12_SDK_baseurl = "ken"
}
