multiple imputation macro not working

[nmimunro]

Hi
I'm trying to get the multiple imputation macro to work following macro_instructions.pdf, p.8 and using the sample data provided in file prac2full.ws . I get the following error everytime I try it:

I don't have these macros and their documentation to hand, however this error indicates that no level-1 identifier has been defined in the model.
