[Websken]

I've read through many previous posts but still don't understand, or can't
get, this numbering to work.

I would like to start off my numbering with 1a) followed by the next point
1b), etc. Somewhere along the way, I would eventually want to change this to
2a), 2b) etc.

Please can someone explain again in really simplistic terms if this can be
done and how?

Regards,
