I am studying the use of Dynare. I have a model in which there are only backword looking variables. I encountered a problem but I found a useful answer in this forum (Simple first order difference equation). I can run a program with a “dummy” forward looking variable as suggested by ales but I cannot run the program in the snapshot though I am using Dynare 4.0.1. Does any one know what is wrong ?

The error messages are the following:
