javascript radio buttons and drop downs

I have a problem! I have four radio buttons named searchtype. Each button has its own value lets say one, two, three, four. when buttons two through four are selected i want a text box with the text enter city in it. Below that I want a dropdown list with the values a, b, c, d for radio two. e,f,g,h for radio three, and i,j,k,l for radio four. when radio one is selected i want a drop down list with a1,b1,c1,d1, and below that another drop down the same as if radio two was selected.

So now that I have totally lost you, is there anyone who can help me? Thanks in advance. bprego

maybe you should be looking in the "javascript" threads instead of the computer programing ones...
