Hi everyone,
I’m looking for a formula to check if any cells on a selection of 5 are empty. Hard to explain globally, but theorically the formula would look like this: IF (Cell 1) is empty OR (Cell 2) is empty OR (Cell 3) is empty… THEN display  :white_check_mark: 
How can I achieve this on Airtable?
Thanks in advance for your help.
Welcome to the Airtable community!
You want to compare values with BLANK(), and use an OR() function.
IF(
  OR(
    Field1 = BLANK(),
    Field2 = BLANK(),
    Field3 = BLANK(),
    Field4 = BLANK(),
    Field5 = BLANK()
  ),
  "✅" 
)
If this answers your question, please mark this post as the solution. Otherwise, could you please give a bit more details and a screen capture?
An alternate approach is to use the shortcut method for checking whether or not a field has anything in it, by only including the field name. For example:
IF(Field1, ...
is equivalent to
IF(Field1 != BLANK(), ...
To invert the comparison, and see if it is blank, wrap the field name in NOT():
IF(NOT(Field1), ...
is equivalent to
IF(Field1 = BLANK(), ...
Which means the formula written above could also be written like this:
IF(
  OR(
    NOT(Field1),
    NOT(Field2),
    NOT(Field3),
    NOT(Field4),
    NOT(Field5)
  ),
  "✅" 
)
Yet another way is to invert the entire thing. Because you’re checking for any one of those fields to be blank, this will also work:
IF(NOT(AND(Field1, Field2, Field3, Field4, Field5)), "✅")
This only downside to this field-name-only shortcut is when it’s a numeric field. Airtable will read a 0 in a numeric field as false. In that case you would have to compare against BLANK() to correctly distinguish between an empty field and one that contains a 0.
