Thanks ahmedA for your answer! That helped. The code I ended up with was: var loop_count = parseInt("${lm://CurrentLoopNumber}"); var score = parseInt("${lm://Field/1}"); Qualtrics.SurveyEngine.setEmbeddedData("condition", "Amateur"); Qualtrics.SurveyEngine.setEmbeddedData("video" + loop_count, score);I embed the variables "condition", "video1", "video2", and "video3" after consent. This works extremely well.With regards to 4060, I calculated it doing n choose k which is given as n!/(k!(n-k)!). In this case of having say 30 videos to choose from and 3 videos chosen gives 30!/(3!(30-3)!) = 4060.
