Hi,
Yes, you can fix this by using some custom js. Start by adding this to your Custom JS:
// Define the variable outside the function to make it available globally
var multilineEmailVariable = "";
function dffs_PreSaveAction() {
// Update the value when saving - before the email is processed
multilineEmailVariable = getFieldValue("Your_multiline_field").split("\n").join("<br>");
// This function must return true to save the form
return true;
}
Replace Your_multiline_field with your actual field name.
Now change your email template to use the variable like this:
{var:multilineEmailVariable}
Let me know how it works out.
