Stimlist for sound files (case 12705)

[BH84]

Hello,

I am having trouble presenting sound files sequentially from a stimlist.
I want each of the words on the list to be presented for 1500 seconds each.
So for example, I have 3 audio files called: dog, cat, and night.
I created a stimlist called stimlist1.txt and in it i have:

!dog
!cat
!night

In my CVS line, I have &stimlist1 under the stimulus column, 0,0,1 for location, and 1500 for time.

What am I doing wrong?
HELP!
