unable to print the value from email script to email body

[Abdul]

hi,

I am trying to get a value of a variable from a catalog item in an email script and i have to get the last four digits of that number and getting the last four digits of it.

I am sending it to my email body and i am printing it there.

When the email is triggered i am not getting the last 4 digit value.

Below are the code:

Email Script:

(function runMailScript(/* GlideRecord */ current, /* TemplatePrinter */ template,

          /* Optional EmailOutbound */ email, /* Optional GlideRecord */ email_action,

          /* Optional GlideRecord */ event) {

          // Add your code here

          var cardNum = current.variables.card_number_s;

          var lastFour = cardNum.slice(-4);

          template.print(lastFour);

})(current, template, email, email_action, event);

Email Body:

Card Number(s): ${mail_script:Last_four_digits} 

Please help thanks

Hi @Abdul ,

Can you please confirm on which table is your notification running? Also what is the type of the variable card_number_s?

Thanks, 

Rishi.

If you're unsure about how card_number_s is being populated, add some debug logging to verify the value before performing the slice operation: gs.info('Card Number: ' + cardNum);

and If card_number_s is not a string but a number, you will need to convert it to a string before using .slice(). Numbers do not support the .slice() method.

Here's how the final email script should be:

(function runMailScript(/* GlideRecord */ current, /* TemplatePrinter */ template,
/* Optional EmailOutbound */ email, /* Optional GlideRecord */ email_action,
/* Optional GlideRecord */ event) {
var cardNum = String(current.variables.card_number_s);

var lastFour = cardNum.slice(-4);
template.print(lastFour);
})(current, template, email, email_action, event);
