SQL Reporting RTRIM and LTRIM

I have a field in a text box and that combines first and last name. If I didn't use TRIM there was too much space between the first and last name. Now when I add TRIM there is no space between first and last name.

How do I get a space between the first and last name?

here is my current syntax

=(TRIM(Fields!FRSTNAME.Value)+(Fields!LASTNAME.Value))

It prints on the report like this JOHNDOE I want it to show JOHN DOE
