Trying to auto refresh map services

I'm am very new to javascript programming and am trying to autorefresh some layers in my web map. I've attached my code...any insight would be extremely helpful.

The logic looks right. Some things to look at:
1. The syntax of setInterval function: http://www.w3schools.com/jsref/met_win_setinterval.asp
2. Make sure you understand the variable scope in JavaScript: http://stackoverflow.com/questions/500431/javascript-variable-scope
In your code, you cannot access those layers which you created in another function, because they are the local variables. You can either set them as global variables, (normally, you should avoid doing so), or pass it as an argument.
