use of unresolved identifier error

Question

I have implemented a vote feature in my app so that user can vote up a post. I am using a collection view and have put a label and a button . When the button is pressed the vote counts up. I have that code in the cell view controller . This is my collection view controller and even though I have said that votes in the cell I have an error saying

use of unresolved identifier votes

Stuck for many hours. Any help is appreciated..Thank you. In the cellForItemAtIndexPath I have

func collectionView(collectionView: UICollectionView, cellForItemAtIndexPath indexPath: NSIndexPath) -> UICollectionViewCell {


    let cell = collectionView.dequeueReusableCellWithReuseIdentifier("newview", forIndexPath: indexPath) as! NewCollectionViewCell
    //cell.backgroundColor = UIColor.blueColor()


    // Display the country name
    if let value = posts[indexPath.row]["imageText"] as? String {
        cell.postsLabel.text = value
        println("it should be there")

    }

    // Display "initial" flag image
    var initialThumbnail = UIImage(named: "question")
    cell.postsImageView.image = initialThumbnail


    // Fetch final flag image - if it exists
    if let value = posts[indexPath.row]["imageFile"] as? PFFile {

        cell.postsImageView.file = value
        cell.postsImageView.loadInBackground({ (image: UIImage?, error: NSError?) -> Void in

            if error != nil {
            }                
        })

        //  let finalImage = tops[indexPath.row]["tops"] as? PFFile

    }

I get an error from this code.

if let value = posts[indexPath.row]["votes"] as? Int {
    if votes == nil {
        votes = 0}
        cell.votesLabel?.text = "\(votes!) votes"

 }

return cell
}

Also in my cell view I also have

@IBAction func vote(sender: AnyObject) {

    if (parseObject != nil) {
        if var votes:Int? = parseObject!.objectForKey("votes") as? Int {
            votes!++

            parseObject!.setObject(votes!, forKey: "votes")
            parseObject!.saveInBackgroundWithTarget(nil, selector: nil)               
            votesLabel?.text = "\(votes!) votes"
    }
    }}}

Try replacing below lines of code

if let value = posts[indexPath.row]["votes"] as? Int {
if votes == nil {
    votes = 0}
}

with

if let votes = posts[indexPath.row]["votes"] as? Int {
if votes == nil {
    votes = 0}
}
