Feedback doesn't work in the first trial

What are you trying to achieve?:

In my experiment, participants must respond within 3 seconds. But if they reply earlier they can continue (I set it to force end). I just want to give “you were late” feedback when they don’t answer. The code below works but it doesn’t work in the first trial. Where is the error?

Begin exp:
msg=’’
msgDuration=()

Begin Routine:
if key_resp.keys :
msg=""
msgDuration=(0)
else:
msg=“You were late”
msgDuration=(0.3)

Thanks in advance

On the fly: try placing the code component at the very top of the component list in the feedback routine.
