Variable reference is not valid

Update - If you don't need it, you can just delete or comment out the function timer and the script works fine.

After a recent update the script fails with the following error

Iex : At line:261 char:21

•     Write-Host "$Message: Waiting for $($Seconds/60) minutes. $($ ...
  

•                 ~~~~~~~~~
  

Variable reference is not valid. ':' was not followed by a valid variable name character. Consider using ${} to
delimit the name.
At line:1 char:1

Alternatively, you can add a single space after $Message to fix the error. I believe that you simply can't have a variable followed by a colon without escaping it or using one of the special cases for colons. So changing line 261 to the following will make the script work:
Write-Host "$Message : Waiting for $($Seconds/60) minutes. $($ ...

Adding the space works perfectly. Thanks :)
