Suggestions?
It appears the collection is the shopping cart for one user. Since you know
you will want a tally of the individual items ordered, why not keep a list of
distinct items, instead of the line item scenareo. If they scan the same item
twice, it increments that item, rather than creating a new line item. etc...
When you return the Count, it should be the sum total of all items ordered.
There would be no need for the countNumberID function because every
different item would have its 'quantity ordered' already stored, easily available.
