I have a web part page created that contains a user filter and excel web access web part.
Excel web access web part contains a pivot table from a hosted spreadsheet, the user filter web part is pulling a value from SharePoint that is a named parameter in the pivot table.
This works really well when the the pivot table contains information that is relevant to the user, but when the pivot table does not contain information relevant to the user I get an error message.
Is it possible using ECMA Script to modify the error message that is appearing or hide the webpart completely?
