Hi D.,
At 14 months you can 'train' them to go every couple hours (it's more either training YOU or doing "elimination communication", really - not actual potty training).
Generally, they need to be developmentally ready to potty train before you start - it should come from HER - NEVER from YOU - unless you want to sit her on the potty every couple of hours and 'train' her to hold it in between (which, as I said, isn't actual potty training).
However, to do actual potty training she needs to be able to:
1. Tell you she has to go potty (which means she needs to be able to recognize the sensation)
2. Be able to follow multiple commands without prompts - 'go into the bedroom and get your brush and your pony tail holder and sit them on the table, then come sit by mommy'
3. Express an interest in wanting to go potty on the potty.
This is the bare minimum. If she can't do that, then you need to wait until she can do those things.
Good Luck.
