I want to create a field that will tell me, if that field's content is empty (ex: no attachment), it will reflect in another field that it is empty.
For that reason, I have created/tested a Rich-Text field in a form. Let's say that Rich-Text Name is Test1.
Then, I added a computed text field, let's say the name is Test2.
In Test2 field, I set the formula as this,
@If(Test1!="";"Yes";"No")
As a result, in the Test2's field, it does not show me that the Test1's field is empty, even though it has no text/attachment inside the Test1 field.
I have tested many times, and the result is still the same.
Please help me on this matter to solve this problem.
Thank you in advance.
