Hey,
I have the following problem. Within my experiment, I want to exclude people that are suffering from colorblindness. Therefore, I want to terminate the session by redirecting them to a page stating they did not meet the inclusion criteria. I tried to use the stop function, but now Inquisit quits immediately when entering the color check. It now quits even before I enter any digit. I think something is wrong with my condition, but I cannot figure out what exactly it is. Any help would be really appreciated :)

<picture colorblidness>
<picture colorblidness>
/items = ("colorblidness_check.png")
/ position = (50%, 50%)
/ size = (75%, 75%)
</picture>

<openended colorCheck>
/ stimulustimes = [0 = colorblidness; 3000 = text.colorQ; 50=colorQ1]
/ validresponse = (anyresponse)
/ correctresponse = (74)
/ beginresponsetime = 5000
/ stop = [
    openended.colorCheck.responsetext != 74
]
</openended>


<text colorQ>
/ items = ("Please fill in the presented two-digit number:")
/ position = (50%, 40%)
</text>

<text colorQ1>
/ items = ("Here we want to check whether you can see the correct number.
Please look at the picture carefully.")
/ position = (45%, 10%)
</text>

<block testtrialcolor>
/trials = [1= openended.colorCheck]
/preinstructions = (page.welcome, page.consent)
</block>

Hi Dave, 
Is there a way to screen out people after a certain number of failed attempts? In my case, I ask people to search for a target among a matrix of pictures. They are instructed to click on the target if it is present, or the 'target absent' button if it is absent. Currently, they have unlimited attempts: if their answer is wrong, an error message will pop up and they will restart the trial. This will repeat until they select the target. However, is it possible to set the limit to 2 attempts, so the program will terminate after their second failed attempts? Any advice would help! Thanks in advance!

Hi Dave,
Thank you for your answer! What if I want to display a message before the script is terminated? Does the script.abort function allow a customized message?
