I a doing a form and I have to put two validation at the exit of a field. The validation must be done when a go out by tabulation.

The first validation is to make visible fields is a date is write in a specific field.

The second validation is to check a box is the date of reception is higher of the date of acceptation.

Where and how a can do those validation.

Thank you for your help.

The validation event is triggered automatically when the value of the field is changed. There's no need to do it when the user just tabs through the field and doesn't change its value.

You can read here about how to show/hide other fields and how to work with Date objects:

Hi.

I know how to show and hidden field.

But when i write date in a specific field and I go out of the field by tabulation,  I want to make visible four fields. The prog that I use it's not working like usual. Why?

This the same thing for the second validation. The second validation is when I write the the date of reception and at the exit of the field by tabulation this date is higher of the date of acceptation, I have to check a box.

Can you help me?

Thank you.
