Punctuation help please

The '1' needs punct, eg, 1. Like... or (1) Like...

I wouldn't. or
...right first. Establish: (a) who...

I'd agree

Like I said above, full stop perfectly okay but comma very doubtful

Thank you so much for replying so quickly. The brief states that I need to follow the Guardian style guide and it doesn't put any punctuation after numbered lists. It does feel weird to me. I automatically wanted to put a full stop.
So, to clarify, it would be perfectly fine to leave the sentence as it is without changing the colon or putting one behind "establish"?
Thanks again.

If you have the option, I would start another sentence with Establish ...

, first get the basics right.

(Please list the rule that says for numerical formal lists, there is no stop after the number. )

Scroll down to "lists"

Thanks for the response Punkey.

"1 Like with anything you write, get the basics right first: establish a) who ..."

Not atall Where

D'you mean, Mind, like
WILDLIFE: 1. Birds (a) Swallow (b) Robin ....etc... (f) Hawk; 2. Dogs (a) Spaniel (b) Dalmation.....(j) German Shepard

I'm no xpert, Ismy, but I like the '.' too

I thibk, like I said before, Two colons in the same sentence doesn't usually work

By the way I mighta capped 'establish', esp where "." 'stead'a ':'
