Because at the moment I am only able to create list of words…
Many thanks 
Just type in a whole sentence instead of a word.
Exactly!
When I type in the whole sentence or even just two words, only the first one gets picked up.
That is hy I need help.
I have tried “adding a level” but even there I have the same problem, only the first word gets picked up and saved.
What do you mean by “picked up”? It doesn’t get saved? Or you mean the words that are suggested to you from the database? You can ignore those. Just type the sentence in the first field, the translation in the second field and submit by Enter.
