Hi Robert,

last week I had to fiddle with mdx parameters myself. One report had to transfer the chosen member to a second report. This way it worked:

1) The parameter in 'navigation' has to be the UniqueName, not the fields' value - e.g.

=Fields!Receipt_Number_Search.UniqueName

2)You have to manually edit the mdx query of the parameter-receiving report; to correctly translate the parameter use the 'STRTOMEMBER'-function. I modified the query after 'clicking it together'; hence the subcube-definition:

Select

non empty {blabla} on 0,

non empty {thisandthat} on 1

from {

SELECT ( STRTOMEMBER(@DimReceiptNumberReceiptNumberSearch) ) ON COLUMNS FROM [CubeNameHere]))

WHERE ( and so on )

Hope that provides the necessary clue -

Cheers,

Juergen
