Copy and paste information from one workbook to another using vba

Hello i have this coded:

Sub Touroperadores()

Windows("KPI's").Activate
Sheets("Touroperador").Visible = True
Windows("Transfer").Activate

fi = 1
ci = 1
cf = 3
ff = Concentrado.Range("inconc").CurrentRegion.Rows.Count

Concentrado.Range(Concentrado.Cells(fi, ci), Concentrado.Cells(ff, cf)).Name = "Touroperators"
Concentrado.Range("Touroperators").Copy

Windows("KPI's").Activate
TTOOs.Range("inTTOO").PasteSpecial Paste = xlValues **** This is when i get the error code 424 i cant paste the information copied and i dont know why.

What am i doing wrong?

Everything is named as it appears on the code I've doublechecked that.
