Hello R_Lus

random durations have been discussed before. You might want to see if you could use this approach?

Randomize duration of a Routine in Builder

Hi! Participants are presented with pictures and then fixation cross. I need to set duration for the fixation cross from 3 to 3.5 seconds. It should be random each time. I am a complete newby in Python and already tried several codes proposed on the forum. Unfortunatelly, they do not work for me. Could someone suggest a solution?

Best wishes Jens
