help me with my first mission

[Corrosion]

 have finally made my first mission. at least i thought. i have made everything in the OFP COOL EDITOR PROGram found on ofp.info site. well i save the mission to single missions and start but there is no briefing, just the loadout works. the briefing is gone, so are the notes and objectives. i check in my ofp directory, and the files are there. i de-pbo the mission and see the files there. but why are they not in the mission? i really need help with this. i use FDF mod, and the method worked before i got FDF but is that causing it. the mission is built around te mod, so i cant un-use it. PLEASE HELP!!!
please dont tell me to make briefings myself, i dont know how to and it is just too complicated. i have tried. :'(

Hi, this  is LTS-1GT. I found your question on ofpec forum.  So, the question you have problem for brief not show up in game? Are you created mission for FDF? Where you save your mission export? Multiplayer or Single? Make sure your brief need correct link where you put marktarget name.

We need Sherlock Holmes here.

"When you have eliminated the impossible, whatever is left - however improbably - must be the truth."

It is impossible that the file

briefing.html

is in the mission folder because if it was, it would appear in the Mission.     Therefore the file you have in the mission folder is something else.   Either it is not called briefing.html or there is some error inside it that makes everthing vanish.

Take a working briefing.html file from a working mission - any will do, use the one from the Tutorial Mission in the Editors Depot if you like - and drop it into your mission folder.   You should now get the wrong briefing.   Cut and paste between the two briefing files till everything is correct.
