Hi All


I am working with an existing worksheet macro and I would like it
changed to a regular module macro so I can assign it to a button. The
macro is split into a workbook macro and a Private sub module macro.
I want to be able to step through the code so I can see how changes
made effect it. I can’t currently do this.

The macro calculates FIFO for a inventory system and does that
particular task well.

The columns are such.

Date , start Inventory, Units Received, COGS, shipped, end inventory,
FIFO Calc

I want to assign the code to a button. I can’t do this the way it is
set out. I would really appreciate any assistance.

Take care

Chad
