Trying to combine multi fields into one

[sagenp41900802]

I have a multi page form that I would like to pull 3 fields on one form and make them into one

ex Field1= Firstname

Field2=Middlename

Field3= Lastname

They are on page 1 and on page 7 I want the one field to have

Field 4= Firstname middlename Lastname

I do not know anything really about java and am just trying to figure out if I have to use it or is there an easier way

Adobe Acrobat uses JavaScript, not Java.

What do you want when there is no data entered into the name fields or the middle name or first name  is empty? A null string or 2 spaces.

In earlier distributions of Acrobat, there was an example that could concatenate up to three fields with an optional separator character and automatically adjust for missing or no data.

How to concatenate values from fields on a PDF into another "calculated" field?
