Hi, I am looking for a way to add custom validation for two different text entry fields in a matrix table, one with a month range of 1-12 for month, and the second for year range of 1990s to 2000s. Is there a way to validate two separate text entry boxes?

Hi
You can implement the following custom validation.


^(1[0-2]|[1-9])$
Explanation:
^: Asserts the start of the string.
(1[0-2]|[1-9]): Matches a number between 1 and 12. The expression uses the | (OR) operator to allow either a single digit from 1 to 9 or a two-digit number starting with 1 followed by 0, 1, or 2.
$: Asserts the end of the string.
2. Regex for Years (1990s to 2000s):
^(199\d|200\d)$
Explanation:
^: Asserts the start of the string.
(199\d|200\d): Matches a year starting with either 199 and followed by any digit (\d) or starting with 200 and followed by any digit.
$: Asserts the end of the string.
NOTE: This will include years from 1990 to 2009.
