Obtain directory listing of powershell scripts ... then execute powershell scripts in directory

I'ver been banging my head on this powershell script I am working on, not sure what it is I am missing.

What I'm trying to do is get a directory listing of powershell scripts I created and then execute them.

So far I have tried the following:

# Titanium Graph Generation
$TitaniumGraphUpdates = Resolve-Path ..\*.ps1

foreach ($Name in $TitaniumGraphUpdates)
    {
    Write-Host executing the following .. $Name.Path  

    Invoke-Expression (start powershell (($Name.Path )))
    }

What am I missing? another option I was trying was to export the directory to csv import but still unable to execute those scripts.

Any advice or pointers would be greatly appreciated.
