Dumb question about repeating tasks

I know there is a script; I have even downloaded it. Unfortunately, I don’t normally do any work with scripts, and I’m at a loss as to how to put in the variables that I need. Ideally I’d like to be able to put in different time spans for different items, and have them start from the last due date.

Since I’m displaying my ignorance, I’m also not sure how to work with due dates. I love TaskPaper, but I’m definitely still learning–any help is appreciated.

Note: I’m running TaskPaper 3.8.16 on Big Sur ( 11.4)

Can you link to the script you are using. And then can you also post a simplified version of your outline and explain (in concrete example) how you would like the modified script to work with that outline? Thanks that will help get us on the same page.
