Stimuli dissapear in online experiment

URL of experiment: Url: https://run.pavlovia.org/MarinaIosifian/childsaleffects/html

Description of the problem: I have several stimuli (words) which appear in different positions. Positions are specified in a conditions file (e.g., [0.3, -0.3]). However, when I run the experiment online, my stimuli simply do not appear on the screen. All other stimuli appear correcrtly and no error message is displayed. Could you please advise why this might happen?

The issue is solved - I forgot that in the conditions file I should have set the stimulus position in two separate columns (0.3 in one column, -0.3 in another).
