I am guessing it has to do with the current function you are trying to use.
current() can be use to specify an Xpth but not on its own.
Is this within a repeating section? I would think the filters would be fine
without using current.
Are you using a setfield action on the dropdown or using defaults on the
other fields?
Try going to http://www.infopathdev.com and search on current() to get some
examples of how to use it.

Clay,
Thank you for responding. This is not in a repeating section. This is just
a table with fields coming from a SP list.
If I checked the x path box would this work?
I am using setfield in the Get related data rule attached to the drop down
properties.
What filters would be fine without using current ().? Your saying go from
this:
Set a field's value: .=@BCP_Vendor_Name[.=current()]
VIN1=@BCP_Vendor_Name=current()]
To This:
Set a field's value: .=@BCP_Vendor_Name
> > VIN1=@BCP_Vendor_Name
Thanks,
Stacie

If you have a list which returns
ID Name Description
You would have a FormID, FormName, and FormDesc in your main data source
You would have a dropdown, bound to FormID, which used the ID field as its
source.
Then add a rule that would set FormName to Name[FormID = ID] and set
FormDesc with Description[FormID= ID]
So you would use a filter to get the appropriate row of data.
Hope that helps.
Otherwise email me.
