In fact my trial was close - i had put 'value.data',
which was in one example - a small mistake but prevented that to work.

The order was not relevant because

field=lastUpdated
if{
value = 0
equals.field = lastUpdated
negate=1
}
date=d.m.Y

works too.
In fact I would need else-statement too (to print ' - ' if the value is '0')

I had a syntax error with }
