[dba-SQLServer]Sproc not returning records

AXP, SQL2000

I have a sproc that calls a number of other sprocs to fill in a 
table.  Then it uses this table to retrieve records.  If I run it (by 
pressing the ! button in Access) then the table is filled in, but the grid 
that shows the retrieved records has two column headings Expr<1> and 
Expr<2> (three are expected with proper names).  There are the correct 
number of records but all the rows are blank.

If however I run the code to fill in the table first.  Then when that has 
stopped run the code for retrieving the records I get a grid showing the 
correct column names and data.

My next attempt was to have a second sproc that executes the first one 
(without the final select statement), then runs the select statement.  This 
had the same effect as if it was one sproc.

Does anyone have an idea why this is happening?  The code is below.

--Note - up to here works fine.  Next statement not work if run at same 
time as above.
