Query line counter

I need to use a value that I get from DLookUp("[ID_m]";"tbl_ID_MAKS_VARELNORDRE";"[ID_m]") (there is only ever one record in the table) and add +1 for each line in a query result. I have tried for a few hours now, so any help appreciated. Thanks in advance.

The original query result may look like this:

Sample1     Result 234,4
Sample 15  Result 114,3
Sample 27  Result 43,2

I need the query to return, assuming the DLookup value is 200:

201   Sample1      Result 234,4
202   Sample 15   Result 114,3
203   Sample27    Result 43,2


Best regards,
Evert
