Hi there, I want to add a warning message on a virtual column. Here are the steps I did:
► I’ve made a virtual column called [warning]
Type: Show
App formula: " "
Type detail category: Text
Type detail content: Nothing
Display Name: Nothing
I used the same warning message I have in my other column which is …
Valid if: ISNOTBLANK([Item])
Invalid message: “Match size, feature, color or models”
But It did not work, I do not know if I can actually use the valid if inside a show type column or not.
would you plz wrap it for me so I can use it in a proper way. and where I can add it in the in my show column.
Thanks indeed
