It's not THAT difficult to split the values off to individual records in a child table. First, make sure you have a unique value identifying the parent (a serial ID works best for this). Then create the child table with three fields: ChildID, ParentID and Value.
Now, either import the parent records 24 times (each time importing ParentID into ParentID and a different value field into Value), or define a calculation field with 24 repetitions, each returning one of the value fields, and import the ParentID and the calculation field into the child table, with the option to split repeating values into separate records.
Perfect! Thank you very much.
