I'm not sure exactly what your question is but text in this format:

<<Table::Field>>

are called merge fields.  Merge fields are typically used in "mail merge" applications like a form letter.  Here is an example:

------------------

Dear <<first_name>>,

Your purchase on <<purch_date>> of $<<amount>> is now past due...

------------------

Merge fields are read only but if you place a regular field only your layout it will likely be editable.

Did I answer your question?

No you don't exactly know what I mean.

If I am in a file and I want to import from a relationship file the first name and the Last name using the <<... >> the put the two names close to each other, the program doesn't let me write it down.
It is perfect when we stay in the same file but not when it comes from an other one.
I hope I made it a little bit clearer.....
Thank you for trying to help me.

I'm afraid that I'm still in a haze.  Are you trying to name your fields using the "<<" and ">>" characters?

I found out the solution of my problem using the "insert merge field"
Thank ;you
