st: Programming question

["Banya, Winston" <w.banya@imperial.ac.uk>]

Dear All,

I posted this question yesterday and was advised by Nick but am still not
able to solve it. I need to generate a randomisation list for a small
clinical trial. The trial will be in 5 centres and I want 4 strata of people
at each centre. There are 2 treatments and 2 doses. As I stated yesterday I
used the programme before and it worked well but I am unable to understand
now why it is not working. I am attaching the program again and the output I
obtained the last time I used it. What has prompted this is that the person
doing the study has obtained approval to recruit more patients and we need
an additional list. I will be very grateful if you can look at this program
and offer any advice that can help me solve the problem as a patient is
waiting to be randomised. 

I inherited the program and the only change/addition I made was to the
number of patients needed.

Kind regards
