I have two IATs with two alternate versions within each type that I'd like to present to participants.   I would like participants to be randomly assigned to complete one of the IAT types, but randomize which version of the test appears first.  I created two levels of batches; one that randomizes the order of versions, and one that randomizes the IAT type (path leading to the random order batch file).  Individually (the sub-level random order) works, but the master file seems to be getting "stuck"- not loading.  Any suggestions?
