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
