Hello everyone (Dave), 

I am making a study in which I am validating new IAT stimuli against a pre-existing IAT, therefore I have code for two IATs in one experiment. I used the Inquisit Sexuality IAT template code to build both IATs off of. The issue I am encountering is that for whichever IAT goes second, the instructions at the beginning of each block do not show up. I believe this is due to the InstructionIndex from the values no longer being set to 0, however I do not know how to fix it without throwing everything off.

I've attached the relevant code. Thanks so much in advance for any help!
