Millisecond Forums

Hello,
I 've recently had an issue of how to vary time of a fixation point. I need to randomly assign a duration of the initial stimulus (a fixation point) so as to avoid expectancy of a words that follows. My idea is that after presentation of an X the next word would appear, so the /stimulustimes property should be varied. Here's the code I wrote but... it doesn't appear to work. HELP!!!! Anyone!!!!
