Populate Drop-down list based on selection from previous drop-down list

Hello, I'm a pretty new Excel user and I've got a complicated task.

I have several columns in my spreadsheet which I need to populate based on the selection from the drop-down list in the previous column.

For example, I have Appliance as my first drop-down list. The options include: Refrigerator, Dishwasher, Microwave, etc.

I want to populate the second drop-down list (Manufacturer) in the second column with only the values that apply to the selection in the first drop-down list (Appliance). Each Appliance will have a different list of Manufacturers, so I have to create several separate lists and display the proper list when the selection is made.

Moreover, I have to narrow that down even further in the third column (drop-down list Mod#). This list would also populate based on the selection of the second list (Manufacturer) as there could be several options for each selection.

Can someone please give me some guidance on how I might accomplish this? Note: I know nothing about VisualBasic, which I fear may be the answer.

Thank you in advance, P_S!
