If this template helps then use it. If not then just delete and start from scratch.

OS (e.g. Win10): OS 10.14.5
PsychoPy version (e.g. 1.84.x): 2020.
Standard Standalone? (y/n) y
What are you trying to achieve?: present next stimulus depending on the offset of the previous stimulus using variable name.status == FINISHED

What specifically went wrong when you tried that?: I have been using this method for a while. However, after updating to the newest PsychoPy version. I saw this error message “Variable name $FINISHED is in use (by PsychoPy module)”, as attached below. Try another name". I am not sure what the source of this error is. While I was able to run the experiment still, the timing of the stimulus was not quite right.

The way that error works is it looks for certain terms used by PsychoPy to make sure you’re not overriding them - for example, if you called your component “FINISHED” it would cause problems as FINISHED is already a thing. But the way you’re using it looks correct to me! So it’s probably the alert being over-cautious.

In what way is the timing off? Does it appear at totally the wrong time or just slightly out?

@TParsons, thank you for the explanation. Apparently, the timing issue was caused by my laptop not PsychoPy. I was able to fix this delay.
