Multiple key presses for only two words

I have a lexical decision task (word = s or 31/non-word = k or 37). I want participants to make lexical decisions first and then for only two words press the space bar (57) after choosing word or non-word. I also want the program to advance after a certain amount of milliseconds if participants do not remember to press the space bar.

I have created two styles: 10 = min/max of 0-1000! and 9 = 0 min/max.
After the target words I have inserted a blank screen or ~. The blank screen has style 10 and all other stimuli have style 9.

This does not record data for my target trials. Please help.
