Powershell script help

I have a script that has to transfer csv file from local to server. No errors in the log file nor any file is being transferred. Pasting the script here. Help is appreciated.

@echo off
setlocal enabledelayedexpansion
set FtpFile=%~dp0upload.ftp
set CsvFolder=F:\Purple_Top
set CsvFolder=C:\Temp
set logfile=upload.log

set CsvFile=
for /f "delims=" %%a in ('dir /o:d /b "%CsvFolder%\*.csv" ^| findstr.exe "^[0-9][0-9]_[0-9][0-9]_[0-9][0-9][0-9][0-9]_[0-9][0-9]_[0-9][0-9]\.csv$"') do (set CsvFile=%CsvFolder%\%%a)
if not defined CsvFile (
    echo No csv file found in '%CsvFolder%'.
    exit /b 1
)
echo Using '%CsvFile%' as input file.
for %%a in ("%CsvFile%") do (set UploadFile=%%~dpna-converted.csv)

echo Filtering unused columns, writing output to '%UploadFile%'.
powershell.exe -ExecutionPolicy RemoteSigned -Command "& {Import-Csv -Path '%CsvFile%' | Select-Object -Property 'Sample ID No', 'HGB(g/L)', 'PLT(10^3/uL)' | ConvertTo-Csv -NoTypeInformation | ForEach-Object {$_.Replace([char]34 + ',' + [char]34 , ',').Trim([char]34)} | Out-File -FilePath '%UploadFile%' -Encoding UTF8}"

call :ExportDataSection FTP "%FtpFile%"

echo Content of the ftp file:
type "%FtpFile%"

ftp.exe -i -v -s:"%FtpFile%" >"%logfile%"
