If And wrong result

If And wrong result

Hello, 

I want to create a this formula,

If Field 1 < 3 Then Field 2 = Red
If Field 1 > 3 And Field 1 < 10 Then Field 2 = Orange 
If Field 1 > 10 Then Field 2 = Green

I wrote this formula on zoho : 

If(And(${Contacts.Field1}<3),'Red',''),
If(And(${Contacts. Field1}>3,${Contacts.Gestion du stress}<10),'Orange',''),
If(And(${Contacts.Field1}>10),'Green','')

Problem is, if Field1 = 9 for example,
I get this answer : 

','Orange','

I just want : Orange
