Question : Getting Excel Web Access Web Part and filter Web Part to work togther

Hello Experts,
We have a sharepoint site and there is a filter to filter the  contents of web parts using a list of values from SQL Server 2005 Analysis Services cubes.And there is one Excel Web access Web part used to display excel data. When I go to Modify shared web part for this Excel Web access web part  the Workbook tab points to an Excel sheet on site for example www.abc.com\xwz\PQ.xls.. But when I open this Excel sheet from the site where it is poining to which is XYZ\PQ.xls, It has different values then what is displayed on the site.

I have different sites , where this same excel sheet is refered to under Workbook tab for different Excel web access web part but it displays the data different for each Excel web part. I am unable to figure out where is this data coming from? There is a .odc connection to OLAP db on server but I am kind of lost to find if there are any tables under this OLAP DB and don't see any tables. This data has to be coming from a Excel sheet?? which may be I am unable to find. or its coming from OLAP DB? Please provide few suggestions how this Excel web access part works. Thanks

The error clearly states its because of parameter your passing from OLAP cube, its not able to set it correctly. Try without parameters first and see if it works, if possible make all parameters empty string n see if it works and later you can figure out which one is the wrong  parameter.
