Unknown string wanted

I've noticed this occasionally on some events, where the name of the event should be, I'm assuming its user made events on the mod I'm using.
More recently I'm starting to mess around with making my own events and get it everytime.
What causes this (I'm assuming its a lack of title or something)?
How do I go about fixing/preventing it?
Will it cause any problems If I just ignore it (although I'd rather not if its an easy fix.)
I'm asking this now rather then later cos if I have to go back and fix events I thought I'd finished with there's a chance that I may just not bother.:rofl:

You need to add an event-description and a description of the options to Crusader Kings/config/modtext.csv, like this f.e.

EVT_20000_NAME;A steward offers his services;;Ein Vogt bietet seine Dienste an;;;;;;;;X
ACTIONNAME20000A;Hire him;;Nehmt ihn auf;;;;;;;;X
ACTIONNAME20000B;Send him away;;Fort mit ihm;;;;;;;;X

The first line is the event-description and the 2nd and 3rd line are the descriptions of the 2 event-option

I thought I already did that
So what your saying is I cocked up somewhere:rofl:
I'll edit this post when I work out where I went wrong but at least I know I'm on the right track.lol

EDIT.......
sorted, I had a line that was commented out but didn't realise it still needs to end with
";;;;;;;;;;;X"
At least I think that was the problem.
Thank you
