I have a list box with a dropdown list i created for testing and I want to see how can I select a specific word from my drop down list in one cell, and in the next cell depending on my previous selection only shows what that selection is tied to. so for example. E1 I select "DB9 connector". When i go to F1 and go to my dropdown list it will only show all my different DB9 connector problems only and not my other DB9 problems. My list under FI will have hundreds of different type of problem scenario for me to choose from so I want to make it easier by not having to scroll through so many in my dropdown list. how would a code like that look like? And make it a way so people can not free type in these cells but can only choose from what they select. I been wanting to do this for years but could never really get any help on coding.
