I need help getting past this error.

My application was built a long time ago. We have it migrated to PB2022 R3.

I have 2 windows named the same in two different PBLs. Each of these windows calls the same function which is in another PBL. Both these windows work fine separately and have worked set up this way for years. 

The window that comes first in the library list will regenerate fine. The window that comes second will get an error.

     C0052: Bad argument list for function: fnvo_ref_doc_no_retrieve

The calls to the function fnvo_ref_doc_no_retrieve are identical in both windows. 

Any thoughts on why I am getting this error and maybe how to correct?

Thanks,

Teresa
