Help with a trigger

Hello,
I play on aardwolf and need a bit of help.
Not alot of people on our tech channel use mush...yet lol
We have an auction where we can buy and sell stuff.
I want to make a trigger that will write what i buy and for how much into a notepad each time i buy something.
Here is a little of the auction text

selling
Goldenwolf is auctioning a delicious Oreo (Level 62, Num 606). Current bid is 100.

Sold to someone else not you
An ethereal blade SOLD to Auri for 5,000 gold.

Something sold to me
A Crystal ball SOLD to Kinslayer for 1,000 gold.

How can i make a trigger that will put the entire sentance of what was sold to me by using the trigger , say , ummm
sold to kinslayer. into a notepad file and save it as well as append each time it fires.

any help would be greatly appreciated : )

Thanks

Is this more of a log type thing? or just a regular MC notepad window (that gets saved).

I would like it to save to a file i designate.
Haun in aardwolf showd me how to do the scripting part

huan ok, work for me: match text (.* SOLD to Kinslayer for .* gold\.$), send say %1'

Ok now the problem i have is .. i have reg express checked and notepad append.

how can i make it send to a notepad file and save after each append and be able to designate the file it does it to?

Thanks in advance
