Automatically remove entries from one list depending on values selected from another

Hello Forum members!

I urgently need help with something I am unable to solve.

I have two lists. What I want to do is omit some options automatically from the second list depending on some options selected from the first.

Guess this shouldnt be very difficulat but cant get my head around it.

Please refer to sample (Trial sheet.xls)

Thanks

Thanks XOR LX it works.

I also tried using an IF condition in the data validation source for Code 2. That works too!

Thanks for your help.

Cheers
