Someone Please Help Me Edit This Sentence

[topguru]

My first article has been rejected twice because of one sentence. I'm now considering getting rid of the sentence altogether but I have decided to ask for help before I do that.


==== Editorial Information for Your Article: ====
iCloud basically refers to a set of cloud services such as iTunes in the Cloud, Documents in the Cloud and Photo stream[--]all of which are designed to work seamlessly with the new phone, despite storing all content in the iCloud.
==== Editorial Information for Your Article: ====

I really have no idea what the editor means by [--]

Any help will be appreciated. Thanks.

It means add the two dashes between those two words.

Thanks for your quick reply Lysis. However, I'm still a bit confused.

iCloud basically refers to a set of cloud services such as iTunes in the Cloud, Documents in the Cloud and Photo stream--all of which are designed to work seamlessly with the new phone, despite storing all content in the iCloud.

Do you mean I should do the above or use an em dash like this
Photo stream—all of

Thanks again.

I think the editor's system is plain text, so I think he/she meant the em dash and it's showing up as two dashes here. For some reason, editors love them em dashes. lol

Thanks a lot for your help.
