Saving to existing Parse.com object

I am receiving the following errors [1]"Cannot subscript a value of type '[AnyObject]' with an index of type 'String'. [2]Cannot invoke 'saveInBackgroundWithBlock' with an argument list of type '((Bool, NSError?) -> Void)'. I am attempting to save an integer to an existing parse.com column. 

func heatUp(){
    let findDataParse = PFQuery(className:"flyerDataFetch")
    findDataParse.whereKey("objectId", equalTo: objectID)
    findDataParse.findObjectsInBackgroundWithBlock{
        (ObjectHolder: [AnyObject]?, error: NSError?) -> Void in
        if (error == nil) {
                //[1] First error
                 if let ObjectHolder = ObjectHolder {
                    ObjectHolder["attention"] = self.count
                }
                //[2] Second error
                ObjectHolder.saveInBackgroundWithBlock {
                    (success: Bool, error: NSError?) -> Void in
                    if (success){
                        println("successful save")
                    }
                  }
                 }
                }

}

I'm not 100% sure what this code is supposed to do, but...

Error 1: ObjectHolder is an array of AnyObject types. You're trying to get the "attention" index of ObjectHolder which isn't possible. Remember, only numeric values go into the [] of an array for indexing. For example, if you want to get the first value in the array:

value = array[0]

You probably want to get the first PFObject in ObjectHolder using ObjectHolder[0] and THEN do the editing of that column.

object = ObjectHolder[0]
object["attention"] = self.count

Error 2: Again, you're trying to do an array of operations on a list of objects. Using the object you just created above, do:

object.saveInBackgroundWithBlock {...

Put PFObject instead of anyobject (convert it) and for error erase it or dont put it as optional

Change 

(ObjectHolder: [AnyObject]?, error: NSError?) -> Void in

To

(ObjectHolder: [String]?, error: NSError?) -> Void in
