FileMaker 10 Pro Advanced - AutoLookUp

I have a solution that has two fields of data that need to be standardised, for example; Field Name: Town Data: Soller, Søller, Sólle, Sóller I would like these to return = Soller Field Name: Property Type Data: House, Villa, Mansion, Finca, Detached House I would like these to all return = Villa I understand I will end up with two new fields showing the final data, this is fine and what I need. I can provide the whole soulition for you to add this autolook up
