First of all I am following this method of using cascading drop downs http://www.uccorner.com/253/sharepoint/cascading-drop-down-sharepoint-foundation-2010/
On the custom list where I will access the other 2 lists and the cascading function. What column type do I make the fields? Are they drop down column or are they single line of text, etc.?
Thanks in advance for your help.
