In Project Pro how do I check if a task has been baselined?

[Gene]

We are using Project Server 2003 and have a number of Enterprise Task
Text fields that display some indicator to show if the task is on-time,
etc. The problem is when using Project Pro 2003 we have not found a
calculation that recognizes if a task has been baselined. The
Enterprise Task Text filed displays #ERROR if the calculated field
tries to use a non-baselined field in a calculation. Can someone give
me a formula to identified that a baseline field has not been populated
(i.e. Baseline Start has not been populated)?

Pretty funky way MSFT set up Date fields, however, the following is how to
test for NULL date fields.

iif([DateField]=4294967295,"Date is not valid, don't do calc","Date is
Valid!")
