Help modifying a powershell script

Question

Hello,
I have recently been given a task to write/find a script that is capable of performing Full and Incremental backups. I found a script that does exactly what I need, however, it requires user input. I need this to be a scheduled task and therefore I need
the input to be a static path. Here is the script I am talking about:

I have some experience writing Powershell scripts,but I am lost at how this script prompts for Source and Destination paths. I tried modifying the Param section, but this didnt work and up until now I thought the only way you could get a prompt was with
"read-host". Any and all education on this matter would be greatly appreciated. (Side note: I have posted this question  on the forum in which I found it and have not got an answer yet).

Hi Ryan Blaeholder,
Thanks for your posting.
To schedule a powershell script with input value, instead of modifying the script above, you can also try to add the input during creating a scheduled task like this:(save the script above as D:\backup.ps1)
-command "& 'D:\backup.ps1' 'input1' 'input2'"
For more detailed information, please refer to this article to complete:

I hope this helps.
