+xHello, I am attempting to skip a video trial after it has been presented within a block. For example, I'm trying to randomly select 1 out 6 beta videos first, afterwards, watch the remaining videos, both alpha and beta (but not the beta video that was ranomly selected in trial 1). I have the code below, but it doesn't seem to work. <block ABLOCK>/trials = [1= noreplace (beta1, beta2, beta3, beta4, beta5, beta6); 2-12=noreplace(alpha1, alpha2, alpha3, alpha4, alpha5, alpha6, beta1, beta2, beta3, beta4, beta5, beta6)]</block> Thanks for the help! You need to use <list> elements to do that. <list beta> / items = (trial.beta1, trial.beta2, trial.beta3, trial.beta4, trial.beta6) </list> <list alpha> / items = (trial.alpha1, trial.alpha2, trial.alpha3, trial.alpha4, trial.alpha6) </list> <list alpha_beta> / items = (list.alpha.nextvalue, list.alpha.nextvalue, list.alpha.nextvalue, list.alpha.nextvalue, list.alpha.nextvalue, list.alpha.nextvalue, list.beta.nextvalue, list.beta.nextvalue, list.beta.nextvalue, list.beta.nextvalue, list.beta.nextvalue) </list> with <block ABLOCK>/trials = [1= list.beta; 2-12=list.alpha_beta]</block>
