Where do you put a comma?

It's impossible to tell you where to put a comma without knowing the specific sentence! Commas are used in many different ways in English.

To help me give you the right answer, please tell me:

* The sentence you are working with.

* What you think the comma should be used for.

For example, are you trying to:

* Separate items in a list?

* Set off a phrase or clause?

* Show a pause in the sentence?

Once I know what you're aiming for, I can give you a precise answer on comma placement!
