Function support

[sotiris]

Hi,
I have 3 fields, name1,name2,name3.
I want to create a function that i will give a result of multy line field (like
pressing ctrl+enter).
for example, if in one record all of the 3 fields have texts the result
will be
name1 (value of the field)
name2 (value of the field)
name3 (value of the field)

if the name1 field is null then the result will be
name2 (value of the field)
name3 (value of the field)

if the name 2 field is null then the result will be
name1 (value of the field)
name3 (value of the field)
etc
hope that i describe the function as good as i can
