Hi,
Any syntax problem with this? Yes. You can say either 'change' or 'changes' here, although the plural would be more common. However, here are a number of other edits to your sentences.
Are we going to have more change on 'PARK FILE' and then altogether we'll apply all of the changes including the recent ones? I'm confirming just.
Are we going to have (any) more changes to the Park file? if so, then will we apply all of the changes together, including the recent ones? I just want to confirm this.
Best wishes, Clive
