How to take away only one of multiple items [duplicate]

Question

This question already has an answer here:

• Clear item with custom name? 1 answer

I'm making an enchanting shop, where you click a button, it takes away your sword, gives you an enchanted one. But currently, I am using /clear to take away the sword, so if someone has more swords, it takes away all of them. How do I do this? Do you have to add a number somewhere? I am not trying to take away items with custom names, just a normal diamond sword.

The syntax of /clear is:

/clear [player] [item] [data] [maxCount] [dataTag]

To make it only take away one sword, put maxCount as 1.
