Hi,
I have a SharePoint List and its customised using PowerApps just for the look and feel.
I have a column in the list named "Vendor Names" and "Vendor Email Address".
So, I want to build a logic, if there Name or Email address is same then it should prompt and error on save and should block the user from saving it. No need to to prompt for Update.
I read the forums and found out some if and filter loop but all those are built on "Submit" button.
In my form we do not have submit as we are using standard "Save" and "Cancel" options provided on the list.
Appreciate if someone can please help me with the correct code and where that code should be entered?
Thanks.
