Two date fields should have the same value

Initially you need to understand the nature of each formula.

equal: is a boolean formula (returns true or false) and requires two arguments. It compares both parameters and returns true if they are equals or false if not.

date: is a date formula (returns a date object) and requires a string parameter. It tries to convert such string into a date object, which can be populated into a date field.

Additionally can you kindly explain which field has to be populated with which formula? (you can even describe the formula in your own words instead of regular sugarLogic formulas).

Regards

Thanks for the explanation, it looks like I didn't use the right formula. 

The closing date l($icc_closing_date) is always manually added by my colleagues. The first payment date field ($termin_1_rate_c) should automatically take the closing date as the date for the first payment.

So the first payment date field should have some kind of formula to take the value from the closing date field.

Thank you for clarifying the request.

The formula is the simplest possible!

sugarLogic formula for termin_1_rate_c:

$icc_closing_date

Definitely it is only that!!!!

Oh well, that was really simple  I thought formulas always needed some kind of addition. 

Thank you for your quick help!
