javascript array lost in function call

Do you have any idea why the console.log below is showing the value I have stored in the array videoList (itself an array of file locations) 

$(window).load(function(){
    videoChoice = videoList[7];
    console.log(videoChoice); // output: value I have stored in the array (another array)
    setUpVideo($("#video-player", videoChoice));
})

while the console.log inside the called function is showing undefined:

function setUpVideo(element, vid){
    console.log (typeof(vid)); // output: undefined
}

Any help is greatly appreciated. If you need more code just ask. I thought it'd be best to keep my question short and uncluttered but it seems I'm not great at asking questions from my experience here.

Thank you, Niall

edit: I had a look at similar questions here but didn't see any clear answers (probably more to do with my ability to understand them I admit)

Error in line 

setUpVideo($("#video-player", videoChoice));

inside $() symbol jquery treats it as selector.

use 

$("#video-player"), videoChoice);

should give you expected results

Try to do:

setUpVideo($("#video-player"), videoChoice);

instead of:

setUpVideo($("#video-player", videoChoice));

Parenthesis... instead of

setUpVideo($("#video-player", videoChoice));

do

setUpVideo($("#video-player"), videoChoice);
