I wish to compliment you on the radio ad you presented to the committee yesterday. This ad will be a fine complement to our advertising campaign for Wiz our new product. By the time, we have our next meeting you may be able to devise additional plans for promoting our new product.
Wes Perkins, manager of the Kitchen
Appliances Division advised me this morning that in April, they will be releasing a new device for chopping vegetables. If possible come to my office at 9 a.m. on Wednesday, June 30, to discuss possible advertising plans for this new device. If you cannot come at that time call my assistant for an alternate appointment.

Needs a comma after first use of Wiz. Delete comma after By the time. Add comma after division. Delete comma after April. Add comma after possible. Delete comma after Wed. Add comma after time.

I am confused as where to put the comma at that you stated in the first sentence.

sorry that i put Jay as my name was talking and typin at the same time
