Style requested 0 not in drt (case 441)

[kynamenthia]

Hi,
I am developing a modified stroop with a forward mask. I've looked at all the examples, and I still am getting an error message above, or that there is a missing value in a time column.
I am attaching it here. Can you see anything obvious?
thank you
kyna

You are missing a value in cell I2 of the attached file. Put the appropriate amount of time for that cell and try running the input file again.
