Hi all,

I am hoping I am just missing something small here. I have a study I plan to post to the web with a stagaring 32 conditions. I have written <exp> and <variables> files defining what I want to happen for different participants. Not all participants will have the same number of blocks (I pasted a short version below).

What happens when I am practicing with the deskop edition and I enter a subject number of "2", I can't and I get an error looking for block35. For participants in this condition (so 2, 34, etc.) there are only 34 blocks. When try to enter subject "4", I get an error that it is looking for block 31. If I have a condition that has the maximum number of blocks across all conditions (which is 35), those subject numbers seem fine.

My question is: can you have <exp> for different subjects that have different quanities of blocks? If so, does this need to be specified in the <exp> or elsewhere? If not, should I create some kind of dummy block so that each of my <exp> will have 35 blocks?

Thanks,

Susan
