Date Format Problem

Have you set the format for the field?

You can handle it better in the server-side page instead on the client form.

i did set the format into mm/dd/yy,
but it only shows a warning instead of changing the format automatically.

What is the exact error that you are getting?

Are you using LiveCycle Designer (one of 2 programs within Windows Acrobat Professional that can create forms)?

If so that creates a different type of form than Acrobat's Form Tool.

I want to type in some numbers, 010101, for example, and it will be changed into a date format automatically, (010101->01/01/01).
If i set the format as mm/dd/yy, when i type in some numbers, it only shows a warning saying that the format should be mm/dd/yy, instead of changing the format of the numbers.
thanks you for helping me anyway.
im not using livecycle designer.

The edit characters are important to separate month day and year fields when users do not enter the full 6 numbers. The use can use spaces, "-", ".", or "/" as a separator. You could try to write a custom keystroke, format, and validation routines to allow for this.
