Millisecond Forums

Hello, 
Actually this is my second time to deal with inquisit, anyhow i'm still facing problems.
last moth I've coded a priming lDT experiment, Anyhow the results were not sufficient because the randomization didn't work well.
I had 30 prime words, 30 target words and 30 non-words. Thus 3 text stimuli.
it was supposed that each prime word appear twice, once with the target word and other with non word randomly. and they must have the same item number.
FOR EXAMPLE: the software was supposed to pick up randomly the prime word number 9 with the target word number 9. then the prime word 3 with nonword 3. then prime word 11 with nonword 11. then prime word 2 with target word 3. (did you get my idea) 
but the randomization didn't work well at all.  (some time the prime word appeared three time with non-words ......)
so i solved this problem by doing the randomization manually. So i had two text items one for the prime words (i typed each word twice and randomized them. and the other text item has included the the words and non words mixed together.
that also led to another problem which was the correct response button. I determined the (/ and Z) as valid response but when i code the trail i determined one of them as the correct response which means that have of the words were tagged with the wrong button. so i ignored my participants responses whether they were correct or not and analyzed their reaction time. 
plz if you have a solution for that tell me I'm so desperate.

NOW i have almost the same problem with my new experiment.
i want a prime picture to appear twice once before a target word and other before a non-word in random pairs so pic 3 appears with word 3 then pic 10 appears with word 10 then pic 7 appears with non-word number 7.
but when ever i Run my script i get the message " could not locate element prime-pic"
ps: i converted my pics to .bmp extension and saved them in the same file as i saved my script. (i don't know if i have to do other things)
what i want is to start my trail with a
1-fixation point ( appears for 700 msec)
2- prime picture (appears for 50 msec)
3- a word or non word (appears for 300 msec)
4- blank shape that covers the words ( here participants can decide whether a string of letters is a word or non word)   
i'll attach my script.
i'm ignorant in computers.  

Thank you in advance.
