[kepler-users] Help with this workflow...?

[José Román Bilbao Castro]

Hi all,

I have been all the week trying to construct a workflow which just  
takes an
optional parameter. If the parameter is present, it concatenates the  
parameter
with another string and outputs it. If it is not present, just put an  
empty string.
At htis moment I am not able to make it work and don't know which kind  
of
director I need to use...

Could you please help me with that?.

Thanks in advance,
Jose.
