I'm having trouble with the field content when defaulting or setting a field with another field value, for example:
Default F[Short text] &cell[Table,Short text,1]
The problem is that if the field value contains words seperated by blanks, then I'm only getting the first word. What is the way around this problem? Also, is it possible to concatenate values from two or more fields into one field?

Concatenation:
Yes this is possible; example:
Default F[Short text] "abc: &cell[Table,Short text,1]
&cell[Table,Short text,2] "
