I've tried using the instructions in this link
https://help.forumotion.com/t135804-how-to-add-a-poll-to-a-specific-topic?highlight=how+to+create+a+poll

After clicking "add" to the forum where I want the poll, there are no options for setting up the poll.
So what have I possibly done wrong ?

Hi there, @Bignuggs.

You create the poll inside when creating a new topic or editing the first post on an already made topic. Underneath the editor, you will see...
Poll Question: That is basically the title of the poll.
Poll Options: Enter choices and separate them by a line break. Maximum number of choices : 10.
Run Poll For: This simply means how many days you want the poll to run before expiring. Blank means indefinitely.
Multiple Choice: You can have the option to have the poll be a single question or have it multiple choice where you can select more than one option when voting.
Vote canceling is allowed: Pretty self-explanatory.

After you selected your options and create the topic, the poll will always be at the very top, on every page.

Hope that helps!

Thanks for the response, it's fixed now. Luckily one of the Admin team for our forum was a better tech head than me.
Cheers

Glad you got it fixed. Have a good day!
