[InStr]dove sta il trucco di questa funzione?

Ciao, sto facendo una verifica sui campi di un form. Voglio verificare se nel loro name esiste la parola required, ma facendo la verifica, noto che ci sono un paio di campi che vengono considerati con tale stringa, come mai?

FORM

codice:

Codice Asp

codice:

Dim Testo
For each objCollItem in Request.Form
	'Verifico se il campo che sto analizzando
	if instr(UCASE(objCollItem),UCASE("required")) > 0  Then		
		Testo = "" & Testo & objCollItem & " : " & Request.Form(objCollItem) & "
"'chr(10)
	else
		Testo = Testo & objCollItem & " : " & Request.Form(objCollItem) & "
"'chr(10)
	end if
Next
Response.Write(Testo)

ad esempio il primo campo nascosto del "success" lo comprende tra quelli con required compreso.
