What are you trying to achieve?:
I am trying to get an image to appear over a video at different time points based on a condition file. The videos cycle through randomly based on a conditions file. There is then an image with the header polygon and i have then put in start_time as another header.

I have tried putting $start_time in the start box but to no success when set as both seconds and condition.

What specifically went wrong when you tried that?:
This is the error message I am receiving, I will an example of one of the condition file below but the whole experiment has quite a lot of video files so I won’t be able to upload all of them.

Start and stop times are already treated as code so you don’t need a dollar sign
