Copy, count files, test path, process indicator and System.IO.FileInfo

Question

I found this, sctipt, that I try to re-write.
As it is, it creates sub folders in the targetfolder, which I found out how to stop it from, by deleting the "\" backslash sign in line 9.
But what I also want is that subfolders if such should exist, also gets copied from $source to $target folder, as of now this doesn't happen. Reason why I chose to try to re-write the script is basically, I can read what it does and I like all the flashy
Things like counting and that it shows the percentage of the processbar AND the processbar :).
I just don't now how to re-write it proberly. By the way nothing should be re-named in the targetfolder every thing from sourcefolder should be "as is" in the sourcefolder.
$SourceFolder = "C:\Color1\TRID"
$targetFolder = “C:\Color2\TRID”
$numFiles = (Get-ChildItem -Path $SourceFolder -Filter *.*).Count
$i=0
clear-host;
Write-Host ‘This script will copy ‘ $numFiles ‘ files from ‘ $SourceFolder ‘ to ‘ $targetFolder
Read-host -prompt ‘Press enter to start copying the files’
Get-ChildItem -Path $SourceFolder -Filter *.* | %{
[System.IO.FileInfo]$destination = (Join-Path -Path $targetFolder -ChildPath $_.Name.replace(“_”,“\”))
if(!(Test-Path -Path $destination.Directory ))
New-item -Path $destination.Directory.FullName -ItemType Directory
[int]$percent = $i / $numFiles * 100
copy-item -Path $_.FullName -Destination $Destination.FullName
write-Progress -Activity “Copying … ($percent %)” -status $_ -PercentComplete $percent -verbose
$i++
Write-Host ‘Total number of files read from directory ‘$SourceFolder ‘ is ‘ $numFiles
Write-Host ‘Total number of files that was copied to ‘$targetFolder ‘ is ‘ $i
Read-host -prompt “Press enter to complete…”
clear-host;

Yes I want to overwrite existing files, since backup is taken care of by another script.
Now I encounter this error when trying to use your write-progress example:
Get-ChildItem : A parameter cannot be found that matches parameter name 'Files'.
At line:3 char:51
+ $Files = Get-ChildItem -LiteralPath $SourceFolder -Files

Supply values for the following parameters:
Process[0]:
Here is the script as I thought it should look like:
$SourceFolder = "C:\Color1\TRID"
$targetFolder = “C:\Color2”
$Files = Get-ChildItem -LiteralPath $SourceFolder -Files
$NumberofFiles = $Files.Count
$Files | ForEach-Object -Begin {
$FilesCopied = 0
-progress{
Write-Progress -Activity "Copying Files..." -PercentComplete [int](($FilesCopied/$NumberofFiles)*100) -CurrentOperation "$FilesCopied files copied out of total of $NumberofFiles files" -Status "Please wait."
"$((Get-ChildItem -Recurse -File -LiteralPath $SourceFolder).Count) files will be copied to $targetfolder"
Read-Host -Prompt 'Press Enter to Start Copying...'
Copy-Item $SourceFolder -Recurse -Destination $targetFolder -Force -verbose
$FilesCopied++
# What is wrong now?
