Variable orientation produces NoneType error

Hello,

no $-sign in orientation. But anyway, orientation does not determine the position of the stimulus on the screen, but its orientation in degrees. See here

Change orientation of Polygon (Triangle) across trials: Flanker Task

If this template helps then use it. If not then just delete and start from scratch. Windows PsychoPy version v2021.2.3 I am aiming to use an excel spreadsheet to adjust the orientation of a polygon triangle from left to right (orientation 270 or 90 degrees). To do this on multiple trials I will use a spreadsheet but I don’t know how to input this information into the spreadsheet so that the trial loop will read it to change the orientation of the polygon? Mnay thanks, Seline

Best wishes Jens
