Where is the cursor when you get the error?

Are you getting a syntax error when you attempt to save the formula, or when you try to execute the report?

The first record has no previous value, so I would change your formula to:

WhileReadingRecords;
Not OnFirstRecord;
stringVar NoPo :=IF {ApTrPoDt.cNoPo}=Previous ({ApTrPoDt.cNoPo}) then {ApTrPoDt.cNoPo}+',' else '' ;

If this does not work, try changing your evaluation time to WhilePrintingRecords.

Why are you using "WhileReadingRecords" in your formula???

There is no sorting/grouping during this process so any references to previous records is boggus.

You should use "WhilePrintingRecords" and a formula using previous records probably belongs in a group header not a page header...tellus what you are trying to do by sample output wanted.
