he doesn't want that

[navi tasan]

1) You shouldn't help him with his homework if he doesn't want that doing.
2) I cleaned his shirt because he wanted that doing.

3) You shouldn't help him with his homework if he doesn't need that doing.
4) I cleaned his shirt because he need that doing.

Are these sentences correct?
If they are, are they acceptable in formal English?
Are they regional?

Try again @navi tasan Are you trying to use the word “done” instead of “doing”?

Perhaps:

You shouldn't help him with his homework. He should do it himself.

I don't think "doing" works there.

What you wrote in post #1 is incorrect, but these are possible.

1) You shouldn't help him with his homework if he doesn't want you to (do so). that doing.
2) I cleaned his shirt because he wanted that done. doing.

It's not natural with "that". In BrE, we sometimes use "... it doing".

Helen: I need my car washed.
Sarah: I can probably do that. When do you want it doing?

It's certainly informal and I don't recommend that learners use it. Just learn to recognise it.

I would expect:

When do you want it done?

Or:

When would you like me to do it?

(The likely response: "Now." )
