Not Writing First Name

[Matt2218]

Hi,

Currently, I am using the following code:

ChimpKit.sharedKit().apiKey = "******************"
let merge_vars = [
"FNAME" : "Test",
"LNAME" : "Name"
]
let params:[NSObject : AnyObject] = ["id": "", "email": ["email": "[email protected]"], "merge_vars": merge_vars, "double_optin": false]
ChimpKit.sharedKit().callApiMethod("lists/subscribe", withParams: params, andCompletionHandler: {(response, data, error) -> Void in
if let httpResponse = response as? NSHTTPURLResponse {
ALPLogInfo("MailChimp reponse status code: (httpResponse.statusCode)")
}
})

It works as desired, except that the first name is being left blank. The last name and email are writing ok, any thoughts on why the first name is being left blank?

Thanks
