Error: Subreport could not be shown

I have a data dictionary report. It lists table & column definitions, then
has a subreport in the group footer to pull up dependent objects (the only
way I could get more than the first dependent object to list). The report
has parameters where you can choose to look at All Tables or individual
tables in the DB. It passes this param (@.tblName) to the subreport.
When I preview individual tables, the subreport works great! When I preview
"All Tables", the subreport works on some tables, and then has that error
listed after other tables. Even tables that it works on fine individually
can have this error message.
The data set for the subreport is called TableDepends and uses the following
code:
---
Declare @.objid int
If @.tblName <> 'All Tables'
Begin
Set @.objid = Object_ID(@.tblName)
if exists (select *
from sysdepends
where depid = @.objid)
begin
select distinct 'name' = (s.name + '.' + o.name), @.tblName as TableName,
type = substring(v.name, 5, 16)
from sysobjects o, master.dbo.spt_values v, sysdepends d,
sysusers s
where o.id = d.id
and o.xtype = substring(v.name,1,2) collate database_default
and v.type = 'O9T'
and d.depid = @.objid
and o.uid = s.uid
and deptype < 2
End
End
---
It's weird that this code works in some parts of the main report when I make
@.tblName = 'All Tables' in the main report, but then doesn't parse on other
parts of the main report. And I can't figure out how to do an ELSE clause
that still lists all table dependencies due to the whole Object_ID issue.
Any suggestions?
Thanks,Did a little more looking around. It appears that this error renders in the
Preview tab of Report Designer at Page 6 (and above) of 52 pages. The first
5 pages render correctly. So, I guess my question is whether or not the
Designer can handle all those re-renderings of the subreport.
On the first 5 pages, it doesn't matter if there's 1 dependency or many
dependencies, they all seem to render fine.
Thoughts?

Finally found the ReportServer Error Logs. Here are the error messages I'm
getting:

This error comes up in the log for every time the subreport tries to print
and can't. Anyone have any ideas how to get around it?
Thanks!
