My pasted Javascript does not work!

Hi,

I pasted my javascript but doesnt work: the task is not ready yet.

My script:

It is modelled after the forward digit span test described in Woods et al (2011) [https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2978794/]. However, users can easily customize this test for their own purposes. Easily customizable variables have been listed below. For further changes to the test, knowledge of JavaScipt may be required. For smooth functioning of the test, make sure all the associated github files within the repository have been downloaded (especially the folder named 'jspsych-6.0.4'). Results from this test will be automatically downloaded into the downloads folder of your desktop. For further details, please refer to the README. */

//----- CUSTOMIZABLE VARIABLES -----------------------------------------

file_name = null // file name for data file. if null, a default name consisting of the participant ID and a unique number is chosen.
local = true // save the data file locally.
// If this test is being run online (e.g., on MTurk), true will cause the file to be downloaded to the participant's computer.
// If this test is on a server, and you wish to save the data file to that server, change this to false.
// If changed to false, ensure that the php file (its in the directory!) and the empty "data" folder has also been appropriately uploaded to the server.
// Incase of problems, feel free to contact me :)

INSTRUCTIONS

This is the digit span task.

In this task, you will have to remember a sequence of numbers presented on the screen one after the other.
At the end of each trial, enter all the numbers into the onscreen number-pad in their correct order.

Example: if the sequence is '7 4 5 1', enter '7 4 5 1' in this exact order.

You will now be given practice trials to help you understand the task.
Press 'Next' to start the practice trials.

If you have further questions about the task, ask the researcher now.
If you are clear about the task, click 'Next' to proceed to the main trials.

Thank you for your participation in this task.

Maximum number of digits recalled correctly was ' + highest_span_score +'.

Maximum number of digits reached before making two consecutive errors was ' +consec_error_score+'.

Please tell the Research Assistant you have completed the task.
