Setting NBT

[WiebeHero]

So i have been working with nbt for a while now and i am starting to understand it but 1 thing isnt working very well.
The error is: a types.compound cant be set to anything
Hope you can help me with this!

set nbt of clicked item to "{AttributeModifiers:[{AttributeName:""generic.attackDamage"",Name:""generic.attackDamage"",Amount:10.0,Operation:0,UUIDLeast:324464,UUIDMost:15453,Slot:""mainhand""},{AttributeName:""generic.attackSpeed"",Name:""generic.attackSpeed"",Amount:-3.6,Operation:0,UUIDLeast:8055,UUIDMost:772149,Slot:""mainhand""}]}"
