Help please! How many trials am I allowed to create?

Hello,

I am a beginner and started doing an experiment ( fill in the gaps) by using textboxes for typed responses. I have 42 sentences which means I need 42 trials. However, when I run the experiment it stops in trial 13 I tried to see what the problem is but I couldn’t find any solutions. Another thing that I would like to ask is that I had the mouse as valid click ( on click) to check response time but when I open the excel sheet I am not sure where the reaction time is. Is it mouse.x or mouse.y?

Thanks !!

With 42 sentences you should have one trial in a loop. If you have a mouse component then the RT should be saved as mouse.rt
