I have a RegEx created and tested in regex platforms, this one:
If I check its functionality the result is okay, you could check it too in this link https://regex101.com/r/ocDofm/1/.
The problem is that, when I implement it into a Validation Rule for a Specific field, it does not work. My Validation Rule is :
REGEX( Email__c, ';.+$')
And, if I put the same text that I use on regex101.com web, the Validation Rule does not run. For example, if I open Email__c field, which is a Long Text Area field, and I put this text;
email@example.com;firstname.lastname@example.org;and so on...
Validation Rule should work and error message should appear, but it happens nothing.
Any idea? Thanks.
EDIT: There is an example of the text that I want to be possible in the Email__c field:
email@example.com; firstname.lastname@example.org; email@example.com;
So, the next text, should fire the Validation Rule:
firstname.lastname@example.org;a email@example.com; firstname.lastname@example.org;
