lookup field ID in custom template report

lookup field ID in custom template report

Hello

I have a Master Form, where each records is referenced by a unique "String" data name, let's call it " Record name".

This form posseses a " Subform" which I use to report occasionnal errors in the data from the " Master form". I want this Subform, to trigger "send email" workflow, with a dedicated " Custom template" based on this subform datas

However, when I reference the " Record Name" (which is a lookup from Master form), the result displayed in the sent mail is containing the underlying record  ID, not the "string" name.

How can I make the custom report make appearing the " Record name" instead of " record ID".

Many thanks to all for your answers !
