great !!! it's working perfect now ...

but one question, how do we reward users ? i mean, i want the user to watch as much videos as he wants by touching a button, but how do i reward him? im not sure how to use the blocks because in the youtube video of the first page is for only one view, if i want to show more than one video...how do i reward users?
edit 1: nevermind, i got it working

i will implement this in my games and let you know about my results

edit 2: i'm having an issue with rewarded videos. i load an ad when i enter the scene where my "video button" is. it loads almost instantly the ad. When i click the video button the pop up message shows and if i click the yes button i see the video and i load another video right after the first one (assuming the user will want to watch another one) and it also loads in a second. But if i click the video button and i click the "no" button and then i decide that i want to watch a video it doesnt load as fast as before, i have to wait 2-3 min....... why is that?
edit3: the problem is the block "......ad is available....."... for some reason it doesnt trigger correctly sometimes... i removed it and now i can show ads as soon as i load them..
