Hi All,
I have an attachment control on a SPO list form in Responsive designer. I am trying to add a rule to the control to invalidate the form if there is no attachment. So if a user chooses a specific value in a different control, then this attachment control should be considered for validation, if not then it should be ignored. I tried a bunch of formulas in vain. The attachments item properties is null as it's a new field and there is no value.
I see a {self}
in Named controls. How do I use this to check if there is an attachment uploaded or not. Below doesn't work:
{self} == FALSE
{self} ==""
Any help is appreciated.
