Need help making my program updater

term.setBackgroundColor(colors.lightGray) -- Sets the background color
term.clear() -- Clears the screen
term.setCursorPos(1,1) -- Resets the position of the cursor

textutils.slowPrint("Welcome to Dutch's Update Program,") -- Slowly prints a message to the screen
textutils.slowPrint("Or DUP for short.")
sleep(2) -- Puts a pause between the commands
print(" ")
textutils.slowPrint("Using this Program you can easily Update")
textutils.slowPrint("any supported Program!")
sleep(2)
print(" ")

if fs.exists("dpps") == true then
	textutils.slowPrint("The following Programs were detected:")
	sleep(1)
	continue = true
else
	textutils.slowPrint("No supported Programs detected")
	print(" ")
	sleep(2)

	term.setBackgroundColor(colors.black)
	term.clear()
	term.setCursorPos(1,1)
end

if continue == true then
