Email validation

[lily]

I wanted to validate email addresses and I found a solution in this forum, however, I used the same solution on two forms.  The first form works and the second form says invalid email even though I am using the correct format.

This is what I did.  On the email field, double-click, then Control Settings - Single Line Textbox, click validation, then clicked yes for use regular expression, then in the regular expression box, I have the following.  \b[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}\b 

I also attached screenshots.  I don't understand why it works on one form and doesn't in another.  Is there something I am missing?  Thank you.

What is the email address you are testing?

Try copying/pasting from the expresstion that works, but paste it on notepad and then copy it again.

Hi.

Instead of [A-Z0-9]{4}, use lower case [a-z0-9]{4}

Nintex Email Validation Control Settings - Single Line Textbox --> Validation --> Use a regular expression : Yes

Regular Expression :     .+@.+(.).+ 

Regular expression error message : Enter a valid email address

Code .+@.+(.).+

@bf_parvaz ...use below expression:

^[A-Za-z0-9](([_\.\-]?[a-zA-Z0-9]+)*)@([A-Za-z0-9]+)(([\.\-]?[a-zA-Z0-9]+)*)\.([A-Za-z]{2,})$
