Different number of conditions

Hi,
I’m working on project in which I show two different types of stimulus. After each stimulus I want one of three different information to be shown. Both stimulus and informations need to be shown random (not fullRandom, just random). I have a loop and in Conditions frame I have a file, which specifies the parameters and conditions. It looks like that:

I set loop Type to Random. It is working right now, but not exactly as I want it. It is showing one of colors and than one of information, but sometimes one of the colors (e.g. Blue) is shown more than two times in a row. How can I change it?

Hi,

Could you perhaps upload your input file?

Thank you,
Jan
