Thanks again. And sorry to bother you again. I got the random number
presentation part done. However, i am not sure how could I present this
random number before a word...it is not totall the same as a prime-target.
My prime and target are independent to each other. That is, a word stimulus
does not always have a same number with it all the time.

Basically what i need is :----

1. A random number shown (1 sec and then disappear)
2. A stimulus word shown (disappear after Ss make a response)
3. Ss makes another response about the number
4. Goes to Step 1 after step 3

My problem now is that I do not know ho to link my random number list to a
specific procedure.

How should I fix it?  Thanks a lot!
