Hello, I'm using NPrinting 17.3 connecting to a Qlikview document.
I'm able to create "simple" reports in excel.
When I add a page to my report the following error appears and I'm not able to create it. The error occurs both in the preview area of NPrinting Designer aswell as if I run the report (email distribution).
It look like you are trying to put <PAGE> entity in your excel spreadsheet which obviously has to have unique values. Do you have one Sheet in your Workbook or multiple. If multiple - then maybe one of existing sheets has the same name as the value under the field you are using for <Page> entity?
putting bigger snapshot would be more helpful with:
sheet names visible
field values from field used in PAGE entity (if you are using it)
