Hello, 

I have an online study and I chose the subject numbers to be sequential but there are many missing numbers, could you help with this?
I have six datasets but the subject numbers are 2, 5, 29, 31, 38 and 45.
It is very important that they are sequential (e.g. 1, 2, 3) because I have a counterbalancing script based on odd or even subject number.
My study is : https://mili2nd.eu/artb

Thanks,
Katrina

Whenever somebody opens or refreshes the start page, the sequential subject number generator ticks forward and that person consumes a subject number -- regardless of whether that person ends up actually starting the experiment or not. That is the normal and expected behavior and would be the reason for any gaps you're seeing.

That's for you reply. This makes sense for the subject numbers of the study mentioned above, however, I just did a triak run of a new expt and the first subject has the number: 719610845.
