I have a worksheet used for inventory. In Column A is the quantity (to be entered manually). In Column B is the product description. In Column C is the price of the product, and Column D the total price (column C price x the quantity entered in Column A). At the bottom of the worksheet is a grand total. Also, Column B (products) is grouped into subheadings by the supplier each product came from (for example, row 6 has the title PPG, and then rows 7-137 list every product from PPG).

The calculations in this worksheet work fine. What I am trying to do is, using a macro once all of the appropriate quantities are entered in column A, automatically hide every row of product that does not have a quantity. The tricky part is, if no products under a given supplier subheader are entered, the subheader also hides, and if a quantity is entered, that subheader shows. For example, if I have no quantities under any products for PPG, then the PPG subheader hides, but if just one quantity is added, PPG shows. Also, this list will be constantly updated, new products will be put in and taken out all of the time, so I cannot base the macro on a specific number of rows.

I am new to VB but being forced to learn very quickly due to this project. Any suggestions?
