It is possible to perform calculations in DataPage based on a conditional or IF, THEN, ELSE statement using Calculated Fields.

Here is a conditional calculation involving numbers:

CASE
	WHEN [@field:FieldName]=.25 THEN 0

	WHEN [@field:FieldName]=1 THEN 1

	ELSE 2
END

Here is a conditional calculation involving text:

CASE
	WHEN [@field:FieldName]=.25 THEN 'YOU MUST TAKE ACTION'

	WHEN [@field:FieldName]=1 THEN 'NO ACTION IS REQUIRED'

	ELSE 'OKAY'
END
