Great job, @FreelanceReinh , you have clearly identified the problem and its solution.
@cindyf I'd like to offer some advice that I think will help you with similar issues in the future, that will lead to a faster resolution of the problem, or avoiding the problem altogether.
You should always be reading the log (see Maxim 2). When your code isn't working, you should always be showing us the log for the relevant parts of the code, with nothing chopped out.
Here's what the log says is a similar case (emphasis mine)
WARNING: Output 'parameterestimates' was not created. Make sure that the output object name, label, or path is spelled correctly. Also, verify that the appropriate procedure options are used to produce the requested output object. For example, verify that the NOPRINT option is not used.
I also advise an approach to writing macros, a highly recommended approach, in which you first create working valid SAS code without macros, for one or two iterations. Once you have working valid SAS code without macros, then you can turn it into a working macro much more easily. Had you done this, you would have gotten the proper output with your non-macro code, and then no problems in turning it into a macro.
