Get random item from 2 lists (same position)

Hi everyone!

I have created 2 lists of same lenght. The first one contains a sound and the second one a text, and related to that sound.

I want to get a random sound and it’s related text but I am having trouble selecting the same position (index) in both lists.

How can this be done? I see no index function and have tried with the set property / get property with no result.

Thanks!

this is how you do it
