Unable to convert(x,y) to a number

URL of experiment:

Description of the problem:

I got a conversion problem. Please see the attached photo and excel file for your reference!
I added placement to stimuli list(excel file) and it contains (-0.4, 0) and (0.4, 0) to change position two image stimuli. But they can’t be converted as a number.
How can i fix this problem?
If you add comments, they would be really helpful!

ImageList.xlsx (19.2 KB)

The easiest way to fix this is to use separate columns for the x and y coordinates.

Thank you for all your help.
Columns for the X and Y coordinates were generated. i attached the stimuli list.
But error was still in my experiment… Could you review my code?


Your image doesn’t seem to include an extension. Offline, PsychoPy makes educated guesses but online you need to be explicit.

How can i include an extension. I can’t understand ‘extension’ meaning in this situation…ㅠ_ㅠ

Sorry – I meant a file extension such as .png or .jpg

The photo files are PNG files. But the errors still show up.
