I need help with this please:

On the InventoryAudit worksheet, the cells in range A3:D17 need to be filled in based on the category that is listed in cell B1, "Massage". The table will then contain the information about each product within the listed category. Using named ranges already created in the Inventory worksheet, complete the following:

In cell B3, a formula to retrieve the item within each category in cell B1 needs to be created. Enter an INDIRECT function to return the item numbers by category. The function will reference cell$B$1(absolute) and index the value of the intersection of row 3 (A3) and column1.

Nest the function in an IFERROR function to return a blank cell if no items exist within the category.
