dataset problem

Question

I have a form that it has dataset (dtst) that it has datasource a Referenced dataset (dataset1). The dataset1 contains the 1 master table and 4 views that are details , have put also connections (foreign keys). In the form I have also 2 bindsources that has sources the one the dtst with member the master and the other as source the bindsource that it has the master. In second however bindsource does not give me choice to choose as member one from the connections of master table (in other forms it makes). Rerferenced dataset it is from other solution of studio since I do a client server application.
What is wrong?
I hope to become comprehensible
