make "null" in strings unvisible

[jm29468764]

A result-textfield ist collected from many other textfields, generated with radiofields, checkfields and other textfields.

In the sample each "textfeld" has a delimiter ; at the end.  At the beginn of the sample 5 times null; ist shown. To make an if else - is for each is a havy work (I think I woud need about 20 of it).

Is there an other way possible?
