I have just found CODO and I feel so excited. I am trying to apply it into manage my Zumba class (I am a Zumba instructor) but I met some issues:
- I have a table Card_List including (Card no, Member,…)
- I have a table Slot_List with the Display column is Card No (Lookup from table: Card number column of table Card_List). I tried to write the function for the next column to return the Member of that card. I use lookup() and filter() but it keep returning null array frowning_face:
I think I was wrong at something but I dont know how to embed the doc here.
Can you please help me with that?
