Getting wierd and annoying error while compiling script

[grasscid]

I've been hard at work on my latest mod and I've nearly finished, but there is a problem: I tried to set a script property for the dragonpriestdagger so that it could be added to the players inventory upon completion of a portion of the quest. Something strange happened and now when I try to compile ANYTHING, I get the following:
