null date

Make sure field is setup in the database as NOT NULL or make it required in PHPRunner so user has to enter the value.

Sergey, The fields are set as NULL and are not required because I want the user to be able to leave the field blank. Maybe I don't understand the use of NULL and NOT NULL.

My mistype, I meant to say set field to allows NULLs.
What exactly "I cannot save record without entering a date" means? Any error messages?

If I leave any of the date fields blank and click save the red message at the top of the screen tells me that the date field cannot be blank. This happens on all date fields. I have tested by entering a date in one field at a time and the error happens on each save until I have entered a valid date in each field.

What's the exact error message?
