I think the Título property is the Caption property in English, not the Name property, which, as Scott points out, is on the Otras tab of the property sheet.
As regards the advice you received, a subform control can be given the same name as its source form object, but whether it should or not is another matter. There is a case for naming objects unambiguously to avoid any confusion as to what is being referenced. I would normally use different prefixes for the subform control and its source form object, e.g. frmSubOrderDetails for the source form object and sfcOrderDetails for the subform control.
I have to confess that I do sometimes forget, and leave the subform control named with its source form name. This sort of thing seems to happen more frequently as my 70th year recedes further into the past!
