Only show field if other field is blank

[Rob_Michiels]

I have a field “Processor Info” with a link to a table.
The second field is “Processor” and this field must be visible as long as the link from Processor Info is blank.

I have tried using:
not; processor_info on the Display Depends On but this does not work.

How can I achieve this outcome?

Hi @Rob_Michiels,

Please use it for Display Depends On,

!processor_info

// OR

eval:!doc.processor_info

If more details and a different scenario check it.

@parmartejas, you can try or operations to your conditions e.g. eval:doc.profile == 'Employee' || doc.profile == 'Customer' || doc.profile == 'Distributor' alternate way to achive this is to use frappe’s inList method. e.g. eval: inList(["Employee", "Customer", "Distributor"], doc.profile)

"Depends On" in a new field

eval:doc.field_name != null

Thank You!
