How do I Randomize text placement?

I'm creating a matching card game where you must choose 1 card from each of 2 piles.

I need to know how to randomize the placement of the text on the cards (which card the text appears on).

I've seen a lot tutorials using arrays picking out select frames of animation to achieve this but in my game i need the ability for the person to put in there own words so this method is of no use to me.

Any help appreciated.

Thanks.

Arrays can store strings too. It doesn't have to be a number.

You'll definitely want to get very familiar with arrays and array manipulation if you are doing a card based game.
