Related drop-down lists
I know that it's possible, but I can't find instructions on how to have one drop down lists values depend on a selection in another drop down list. The easiest way to illustrate it would be: I want to have one drop-down list with the maker of a car where you select ford, chevy, or toyota, and then after you select ford, you go to the model list, and you would have choices of only ford cars to choose from. If you selected Chevy you would have options of only Chevy vehicles. I understand how to make the first drop-down list, but I'm not sure how I go about defining the values for the second list. Any advice would be much appreciated!
