Hey vayde,
after some intense testing yesterday night, and some today morning,
I can say: there is nothing wrong with either RSwE or
Gnasirator's MK3 Optimizer.
BUT when i first updated from 1.7.0 to the most recent
1.7.7 of gnasirator's script, i had atfirst the same problem you had,
so i added some debug-code to check the variables, all were ok but the
name wasn't, so i got back to the trader and this Lazy SoB of a trader
was
IDLE, so i send him again on trade-duty and
it all worked! Why it haven't worked before? No Idea!
So I reinstalled both scripts again, to be sure and it worked.
Then I did a clean reinstall(unistalling/deleting all RSwE and MK3Trader files)
and tested it again, and guess what it still worked.
So why it didn't worked right after updating is a little miracle for me,
so i suggest make a clean reinstall of both scripts and it should work.
If it doesn't work right on try stopping your traders and resend them
on trade-duty.
One last thing Gnasirator provides his code in .pck and in .xml files,
just make sure you have either .pck or .xml installed, i suspekt they
produce a conflict if both are installed. I have to ask gnasirator what
this hickup is about, but it should not be the source of this problem.
Edit:

I spent a fair bit of time getting to know your scripts last night and can see how the syntax works now. Although I can't get exactly what I want, I have produced a workaround that I'm pleased with.
Colour coding ST's, LT's and UT's makes them far easier to spot in the menu now

Thanks for a great set of scripts.
if you tell me what exactly you want i can provide some help if it is possible

Greetings Medevel
