Add field value in the value of another field I'm sorry about the title (I think it's a bit confused :D) I can explain better what I need to do.
I have one product with several fields, among which: title,date, description, price, etc... I would add in a field (for example: description) a value of another field (for example: price). I would also that this setting is applied to content type because that field must always belong to the other field, for every content creation.

I searched on Google and it seems the module Token could be a solution but there are many tutorials (and also different among them), so could you help me. Are appreciated other solution, no just Token.
Thank you
You might find Field reference useful. If you're trying to leverage more functionality, you might like to use Entity reference. But you sound like you want embed the value of one field within the value of another, more like concatenating strings?
