Powershell Scripting Assistance : Copy file with error correction

Experts, Looking for additional PowerShell scripting assistance

Function copy-File1 {
Param(
	[Parameter(Mandatory=$true)]
	$FileName
)
	#Drive Locations
	$tempDir = "$($locations.tempdir)"
	$WorkingDir = "$($locations.working_Dir)"
    $tdrivedir = "$($locations.tdrivedir)"
	[string]$filenamenew = "$(&$filenames.cwf_FileNameNew)"
    [string]$Destination = "$(&$filenames.cwf_Destination)"
    [string]$WorkFileloc = "$(&$filenames.cwf_WorkFileLoc)"
	
	#filename Trim
	$FileName = $FileName.Trim()
	If ([string]::IsNullOrEmpty($FileName)) {
		Throw 'Argument FileName is empty!'
	}
	$filePath = Join-Path -Path $tempDir -ChildPath $FileName
	#Identify which File is being Processed
	Write-Host -ForegroundColor Green "Processing File ""$($filePath)"" ..." -NoNewline
	#Test File Destination Path to see if File Exists.. If it Exists Remove it
	If (Test-Path -Path $filePath) {
		Write-Host " $($filePath) Already Exists : Removing File From Temp Location" -NoNewline
		#Error Handling for Remove-Item Command
		Try {
			$itemtemp = Get-Item -Path $filePath -ErrorAction Stop
 			Remove-Item $itemtemp -ErrorAction Stop
			Write-Host -ForegroundColor Green " Successfully Removed File $FileName" -NoNewline
		
		#Add Error Handing for Copy Command
			Write-Host -ForegroundColor Green "Setting $($workingdir) location"
			Set-Location $WorkingDir;
			if (Test-Path -Path $workingdir){
				Try {
					Write-Host -foregroundcolor green "Path Successfully set to $($workingdir)"
					Write-Host -ForegroundColor Green "Copying "$($locations.tempdir)\$filename" to $Destination"
					copy-item -path "$($locations.tempdir)\$filename" -Destination $Destination
					if (Test-Path $filename) {
						Write-Host -foregroundcolor Green "The file $filename was successfully Copied"}

				} Catch {
							Write-Host "Error Message: $($_.Exception.Message)" -ForegroundColor Red;
							Write-Host -foregroundcolor red "$filename was not Copied Successfully"
				}
			
			}else {
					Write-Host "Couldn't set the proper location : script will Terminate";
					pause;
					end}			
		} Catch {
			Write-Host "Error Message: $($_.Exception.Message)" -ForegroundColor Red -NoNewline
		}
	} Else {
		Write-Host " $($filePath) does not exist." -NoNewline
			Write-Host -ForegroundColor Green "Setting $($workingdir) location"
			Set-Location $WorkingDir;
			if (Test-Path -Path $workingdir){
				Try {
					Write-Host -foregroundcolor green "Path Successfully set to $($workingdir)"
					Write-Host -ForegroundColor Green "Copying "$($locations.tempdir)\$filename" to $Destination"
					copy-item -path "$($locations.tempdir)\$filename" -Destination $Destination
					if (Test-Path $filename) {
						Write-Host -foregroundcolor Green "The file $filename was successfully Copied"}

				} Catch {
							Write-Host "Error Message: $($_.Exception.Message)" -ForegroundColor Red;
							Write-Host -foregroundcolor red "$filename was not Copied Successfully"
				}
			
			}else {
					Write-Host "Couldn't set the proper location : script will Terminate";
					pause;
					end}		
	}
}

The code above is a first attempt at a error handling copy file script. While the code appears to be executing correctly, it is not copying the file requested into the proper location as it appears to successfully do.

Thanks in advance for you assistance with this.

Can anyone shead some light on a more efficient way to accomplish this Properly.
