Hi,
I solved this by creating an IF-formula in the table you’re looking up from, saying IF(DateField=TODAY(),1)
.
Then, rather than using a lookup-field I’d use a rollup-field (rolling up on the DateField) with a COUNTA(values)
-formula and setting conditions to only include records where the new ‘If Today’-field = 1.
Edit: Realizing you can make this even easier by skipping the ‘If Today’-field and then just setting the conditions in the rollup-field to Where ‘DateField’ is ‘today’.
