Editvoicepack, creating own phraseology

(Also posted at fsonline.dk) 

Right, first post and I know what you are thinking, another newbie who clearly hasn't gone through the forum. 

Unfortunately, I would just like a bit of help getting to grips with the markers and making my own IFR clearance file. I have already made files to say "FL170" (from FL070 all the way to FL190) instead of "17000" so hopefully this comes across ok. 

I would like to create a new IFR clearance request like this... 

<agent>, <callsign>, <ac_type>, information <atis>, stand <parking_gate_letter><parking_gate_number>, ready to copy clearance to <airport_destination_request> 

So it would read as...

"Manchester Clearance Delivery, Virgin 3046, Airbus A320, information Alpha, stand 18, ready to copy clearance to London-Heathrow"

Now, I thought it worked by adding the "information", "stand", "ready to copy clearance to" sound clips in. I tried this, and the text on the screen in ATC window showed it as I expected, however the verbal dialog only said "information, ready to copy clearance to ......." 

So, I tried markers (albeit not very successfully I imagine) and now the text on the ATC window doesn't show up and neither do I hear it and instead the first I hear is the readback. 

If possible could someone just tell me EXACTLY how to make this one work? Sorry to be a pain, thank you much kindly
