Can anybody tell me what the issue about the code below? Just try to debugg since an hour, but can't find anything. The IF Case is working. For the ELSE case the landingpage always through an error.
%%[ VAR @campaign SET @campaign = RetrieveSalesforceObjects("Campaign", "Id", "Id", "=", "XXXXXXXXXXXXX") ]%% %%[IF RowCount(@campaign) == 1 THEN]%% Success %%[ELSE]%% Error %%[ENDIF]%%
