Need help creating conditional statements in Survey123

[CaseyRagain]

I'm struggling with constructing a couple of conditional statements. The first one is:

1. If {fieldA} is selected 'Yes', then {fieldB}, {fieldC}, {fieldD} and {fieldE} are disabled. (Fields A,B,C, D, E are select_one type fields)

2. If {fieldA} and {fieldB} are selected 'No', then {fieldC}, {fieldD} are disabled except for {fieldE} which is enabled.

Thank you in your advance for your help.

name	relevant
fieldA
fieldB	${fieldA}!='yes'
fieldC	${fieldA}!='yes' and ${fieldB}!='no'
fieldD	${fieldA}!='yes' and ${fieldB}!='no'
fieldE	${fieldA}!='yes'

I think this works assuming that fieldA is only a yes/no response.
