Multiple value choice

Hi Dorota, thanks for your query. This is a difficult one to advise you on because it sounds like it depends on the underlying structure of the database. First of all, double check you have created the lookup field correctly, secondly, in design view on the table, switch to the lookup tab of the field properties and try changing Allow Multiple Values in there. Thirdly, if none of these work, look at the relationships between the tables, particularly if the Lookup is being generated by a one-to-one table relationship anywhere.
