customised slugs using custom field I have a 'Profile' channel that gives the profile of people.

I have 'Last name' as the title, 'first name' and I'd like to use first name in the slug rather than have to add the first name to the title and then need to create another field to store the last name.

I thought, similar to {entry.type} I could've gone for {entry.firstName} but that doesn't work.

Possible?
Firstly I'd recommend splitting the first name and last name into seperate fields. That way in your templates it would look nicer:

{{ member.firstNameField }} {{ member.lastNameField }}


than having:

{{ member.firstNameField }} {{ member.title }}


when outputting their names.

Once you have done that, in your entry type settings you can set the entry title to run off these first name and last name fields:

{firstNameField} {lastNameField}


The slug will be automatically generated from this as well. I may have mis-understood your question, but I hope that helps.
