Hi Guillaume,

I can think of two ways to solve this

1) User Education

You could try adding a placeholder on the service catalog form to make sure they fill it in a certain format. You can configure this under Admin -> Service Catalog

2) Validation
We could try writing a code snippet on the end user portal to make sure the field only accepts only the email format. 

Hi Guillaume, 

Yes, user education isn't always reliable unfortunately :( 

I have a code snippet that could potentially work. Let's continue the conversation over email and post the solution back here if it works?

Hi Guillaume,

It was fun working with you to solve this problem. Sharing the code snippet here for wider audience. Happy to help anyone solve similar problems. I've added comments in the code to explain the functionality.

This needs to be placed inside Page Layout under the Helpdesk Rebranding section

jQuery(document).ready(function(){

validateEmail()  

//Declaring global variable
var isEmailCheck

//targeting the submit button
jQuery(".pull-right .btn-red").on("click", function(){

validateEmail()
console.log(validateEmail())

if(validateEmail() == "Valid") {

// no action required - form will be submitted

}

else {
//shows alert message
event.stopPropagation()
event.preventDefault() 
alert("Please Enter your email in the right format")

}


}) //end on click



function validateEmail() {

//ID of the email address field
var fldName = "#requested_item_values_234_requested_item_value_attributes_mme_profil_que__same_profile_as_email_25000021483"

//A span container to hold the error message
jQuery(fldName).parent().append("<span id = 'errorMsg'> </span>")

//Any time a user finishes typing their email
jQuery(fldName).on("blur", function(){

var ifEmail = jQuery(fldName).val().indexOf("@") //Check if the string has @ to confirm if it's an email address
var ifSpace = jQuery(fldName).val().trim().indexOf(" ") //Check if the string has any unnecessary spaces
console.log(ifEmail + " " + ifSpace)

if((ifEmail != -1) && (ifSpace == -1)) {

jQuery("#errorMsg").text("Valid Email Format")
isEmailCheck = "Valid"

} //end if

else {

jQuery("#errorMsg").text("Invalid Email Format")
isEmailCheck = "Invalid"

}

}) //end blur

return isEmailCheck

} //end function  


}) //end ready
