Hi all not sure if this is the right place to post ampscript help. I have a web formthat is embeded into out website. The form has Name, Email and Phone. I'm tryign to replace phone with or Lead Field Mobile. The field name in Leads is MobilePhone. I get a 500 erro when I change this. In both createSalesforceObject/UpdateSingleSalesforceObject () I've tried ("MobilePhone", @MobilePhone ) AND ("Mobile", "@Mobile") and ("MobilePhone", "@Mobile"). 
 

%%[ 
set @post = QueryParameter("p")
set @Email = QueryParameter("emailaddress")
 set @FirstName = QueryParameter("firstname")
 set @LastName = QueryParameter("lastname")
 set @Phone = QueryParameter("phone")
 set @Email_Opt_in = QueryParameter("Email_Opt_in")
 set @SubmitDate = QueryParameter("SubmitDate")

   
If @post == "y" then 
  
   set @web = RetrieveSalesforceObjects("Lead", "Id", "Email", "=", @email)         

   if RowCount(@web) == 0 then

           CreateSalesforceObject("Lead", 5, "FirstName", @FirstName ,"LastName", @LastName, "Email",@Email,"Status","Open", "MobilePhone", @Phone)
    else 
        row Set @row = ROW(@web,1)
        Set @Id = FIELD(@row,"Id")
        UpdateSingleSalesforceObject("Lead",@id,"FirstName", @FirstName, "LastName", @LastName, "MobilePhone", @Phone) 
    endif 
   
UpsertData("BookTour_Form", 1, "Email", @Email, "FirstName", @FirstName, "LastName", @LastName, "SubmitDate", @SubmitDate)
