Posted on by Kuma0002

In Power app forms - As below I have a field called "Supplier Email" , when user enter the correct email address then below text "Please Enter Valid Email ID" gets disappear and form get submitted. concern is when user enter the invalid Email ID also it gets submitted but ideally it shouldn't. How to restrict the user that only correct email id will submit or else it should not success and throw error message?

I have a formula on "Supplier Email" field >> on Error Message >> Text Property >>

Coalesce(

Parent.Error,

If(

!IsMatch(

DataCardValue8.Text,

"[a-zA-Z0-9.!#$%&'*+/=?^_`{|}~-]+@[a-zA-Z0-9-]+(?:\.[a-zA-Z0-9-]+)*"),

"Please Enter Valid Email ID")

)

Please help to resolve this situation.

Hi @mmbr1606 I am not asking the code, I already have the code with me. concern is that when user enter the invalid input like ex. XXX.com (although it shows red by validation but still that gets submitted) then also they are able to submit the form. If user able to submit it with incorrect data then whats the use if validation to put in there, which property i need to use to restrict them ? I have already placed the code in Border Color , Color and On Change property. Please suggest.
