Greetings,

We are trying to introduce breaks into our experiment and thought of doing it the following way: We have six different trials and we would like to have a (seventh) breaktrial every 'x' amount of trials. We thought of adding to every trial an /ontrialbegin add '+1' to a counter, and add at the end of a trial a conditional branch to the break trial if said trial counter reaches 'x'. At the end of the break trial, we would then add an /ontrialend reset the counter. However, we just cannot figure out how to add this counter; expressions and values don't seem to work... Things like totaltrialcount we can't use because it can't be reset and trialcount doesn't sum over the 6 different trials.

Any tips on how to make this work, or otherwise alternative ideas to implement breaks in this way? (We prefer to avoid using the elapsedtime variable.)

Thanks a ton in advance!
