Unfortunately, it is impossible for anyone here to tell you what your error is without you providing us with your mission file.
That error is telling you that you forgot a = (equals sign) somewhere, which tells me that you must have edited the .sqm file by hand with notepad or some other text editor. That's the danger of editing it without using OFP's in-game editor.
Try undoing whatever your last change was and see if that works. Otherwise, you have to post your file if you want anyone here to fix your problem.
