how to create a formula between saleforces objects ?

Hello,
I have a problem, I want create a formula between saleforces objects but I have an error message.
"Erreur : Le champ Questionnaires__r n'existe pas. Vérifiez l'orthographe"
IF(AND(Respect__c=Questionnaires__r.Respect__c,Respect__c= True),1,0)
My object "Questionnaires__c" is available, can you explain me ?
Thank in advance.

Questionnaire is the child object so one opportunity can have many questionnaires?

select (select name from Questionnaires__r) from Opportunity  // the children.

... and one questionnaire has only one parent opportunity:

select Opportunity__r.Name  from Questionnaire  // one parent

Not enough information to explain the issue, I will do some assumptions
You have 2 objects, one is Questionnaires__c and another one is Respect__c
You have a lookup relationship from Questionnaires to Respect__c
You want to put a formula field on Questionnaires__c based on a field that is on Respect__c object, with a field named Respect__c (same as the object, why not)
Your formula field will be created in the context of Questionnaires__c object in the setup menu. You have to reference Respect__r.Respect__c.
Respect__r is the relationship name to your Respect__c SObject. Respect__c in this formula is the targeted field on the Respect__c SObject

Hello,

For custom objects, look for a pair of entries with the relationship suffix __r:​

If you want to identify Parent and Child Relationships, there is one technique when you want to see (almost) "all" the available API names in only one XML file.

Setup > quick search: API > click on Generate Entreprise WSDL > button: Generate and you get just one huge file in the browser with all the API names of your org.

Verify all the elements with "__r" of your Questionnaire object in the exported entreprise WSDL.

'Questionnaires__r' or something very close (but in this exported WSDL, the found names are always sure).

Hi, thanks for your response.
I want created a formula in opportunité object with the object questionnaire.

I check the wsdl, and the objects questionnaire is true.
<element name="Questionnaires__r" nillable="true" minOccurs="0" type="tns:QueryResult"/>

So why this formula IF(AND(Respect__c=Questionnaires__r.Respect__c,Respect__c= True),1,0)
doesnt work in opportunity obect ,

To anyone who will take the time to answer, thank you so much!.

Plural (most of the time) : <element name="Questionnaires__r" nillable="true" minOccurs="0" type="tns:QueryResult"/>

select (select name from Questionnaires__r) from Opportunity

... should work but that is not your needed formula probably.

Depuis questionnaire :

Singular: select Opportunity__r.Name  from Questionnaire

<element name="Opportunity__r" nillable="true" minOccurs="0" type="ens:Opportunity"/>

Questionnaire is the child object so one opportunity can have many questionnaires?

select (select name from Questionnaires__r) from Opportunity  // the children.

... and one questionnaire has only one parent opportunity:

select Opportunity__r.Name  from Questionnaire  // one parent
This was selected as the best answer
Vincent FruchierVincent Fruchier
Yes the opportunity can have many questionnaire.so I will use 
Opportunity__r.Name  from Questionnaire  // one parent
