What is the problem? Please be detailed.
Hi All,

I am trying to removing a choice from a second list if it has already been selected in the first; i.e
Q1.a What is the main source of income? Rent

  1. Rent
  2. Service
  3. Business
  4. Wage
  5. Remittance

Q1.b What is the next most used source of irrigation on the land? Wage
2. Service
3. Business
4. Wage
5. Remittance
What ODK tool and version are you using? And on what device and operating system version?
ODKCOLLECT V1.18.2

What steps can we take to reproduce the problem?
What is the syntax that needs to be used in the choice filter??

What you have you tried to fix the problem?
income=${income}

Anything else we should know or have? If you have a test form or screenshots or logs, attach here.

Hi @Gajurelsub ,

Check out this thread, I think you can find solution there.

In addition to @dicksonsamwel's, another good reference might be this thread: Choice Filter, which specifically deals with excluding previously selected options.

Actually, its a SELECT_ONE TYPE OF ATTRIBUTE

its a select_one question and I know the choice_filter option which is bit lengthy one, so I was looking for some short code to avoid it

Apart from choice filter is there any other alternative and short code which we can use?
