Millisecond Forums

Hi I am having trouble with randomization of stimulus pairs. The related topic I searched was from the forum Inquisit 2.0. The solution is very cumbersome. Is there any new way to do this with version 5?

For example, I have stimulus pairs A (pic1, pic2;  pic1,3 etc...), B(pic2, pic3;  pic3,4 etc...), C(pic2, pic2; pic1,3 etc...) I want to present stimulus pairs A, B, C the fixed number of trials but random across the block. Each stimulus pair is randomly drawn from lists A, B, C. Is there a way to represent stimulus pairs within a list?

Thanks!
