Need help with AMPscript code

Question

can someone help me to write a code that will retrieve a salesforce object. The name of the field in SF is: Preferred Contact Time The name of the field in MC synced is: Preferred_Contact_Time_Pez__c

This field exists in the lead in SF. Once i get the code, i will put in HTML in an email. Thanks

Im new to AMPSCRIPT and programming in general. Here is the last one i tried,

%%[
    VAR@PreferredContactTime
    SET@PreferredContactTime=RetrieveSalesforceObjects(“Lead”,”FirstName,LastName,Email”,”Id”,”=”,_Subscriberkey) 
    If RowCount(@PreferredContactTime)==1 
        then 
            VAR@PreferredContactTime,@FirstName 
            SET@PreferredContactTime=Row(@PreferredContactTime,1) 
    Endif 
]%%

Answer 1

Try below code

Assuming Preferred Contact time API as "Preferred_Contact_time__c"

 %%[

var @PreferredContactTime

set @PreferredContactTime = RetrieveSalesforceObjects(
   "Lead",
   "Id, FirstName,LastName,Email, Preferred_Contact_time__c",
   "Id", "=", @Id)

if RowCount(@PreferredContactTime) == 1 then
  var @subscriberRow, @firstName, @lastName, @email, @Preferredname
  set @subscriberRow = Row(@PreferredContactTime, 1)
  set @firstName = Field(@subscriberRow, "FirstName")
  set @lastName = Field(@subscriberRow, "LastName")
  set @email = Field(@subscriberRow, "Email")
  set @Preferredname = Field(@subscriberRow, "Preferred_Contact_time__c")
endif
