Display Picture using Enum and Valid If function

[Chee_Hean_Gan]

Hi,

I am trying to do Enum with Picture, i tried using Valid If to let it link to my google sheet image link, it was working fine until i keep editing other column and adding new features, and I did not interupt initial formula and setting, at the end, the image showing “!”.

I got no clue what is happening. I need to use Valid If for create filter
