randomised order of modalities in trials

Hi all, hi Dave,
I have trials of three modalities (word, picture, sound). Is there a way to make sure a maximum of 3 trials from the same modality follow each other (e.g. word, word, word, picture)?
Is there a way Inquisit can detect wether the stimulus in a trial is an <item> (word), <picture> or <sound> and find some code to look for this to implement a maximum of 3?
thankyou so much for looking at it!

Given how you've set the script up, it's not possible. If you had separate trials for text, picture and sound modalities, you could use lists to sample these and use /maxrunsize to constrain the maximum number of trials of the same modality in a row.
