Hi,
all conditions are triggered when you change the value, so for example if you choose option B(value 2):
- Condition 1 hide the 3 fields (Inverse effect)
- Condition 2 hide the 3 fields
- Condition 3 hide the 3 fields


to solve this you can set conditions like these:
Condition 1: if equal to custom value 3 hide the text fields (Inverse Yes)
Condition 2: if equal to custom value empty (leave empty) hide the text fields (Inverse No)

Condition 1 will hide text fields when option value is 3 and show these fields for any other values (inverse effect)
Condition 2 will hide text fields when select is empty but does not do nothing if some value is selected (inverse effect disabled)

Hi

Thank for your help

I have try but i have a problem

3 fields option allway display when dropdown list not selected (see capture file)

impossible to leave nothing value, system requier a value i have write 0

Thank you

Hi,

impossible to leave nothing value, system requier a value i have write 0

This is strange, it should be allowed.
Anyway you can try to change condition 2 from:
Condition 2: if equal to custom value empty (leave empty) hide the text fields (Inverse No)
to:
Condition 2: if less than custom value 1 hide the text fields (Inverse No)
