They cannot be used to invoke other <trial> or <block> elements. That's what the /branch attribute is for, as you've already discovered.

Group: Forum Members Posts: 25, Visits: 120	Hi, I'm intending to show my participants a number of stimulus blocks in randomized order. After each of these stimulus blocks, I want to start another block containing survey questions specific to the stimuli presented in that block, and then select another randomized stimulus block to continue, and so forth. How would I implement this? It cannot be done inside <expt> since the order of the blocks must be randomized. I currently have this, which doesn't work. <block Jantje1> / onblockend = [values.stopblock=0; survey.Jantje1survey;] / stop = [values.stopblock==1] / trials = [1=getstim] </block> note: trial getstim sets values.stopblock to 1 when the stimuli have been presented and the block must end. the survey works when called from <expt> but not when called this way. this does not work either: /branch [if (values.stopblock==1) survey.Jantje1survey] regards, Sercan
