Multiple if statement in SSRS

I'm trying to write the following if else statement statement.

If Fields!CurrencyCode.Value = "EUR" then display this : Code.EuroFmt2Decimal(Fields!InvoiceTotal.Value) + " " + Fields!CurrencyCode.Value

IF  Fields!CurrencyCode.Value = "EUR AND Fields!SoldToCustomer.Value = 121654 then display this : Code.EuroFmt2Decimal(Fields!InvoiceTotal.Value) + " " + Fields!CurrencyCode.Value

else  then Display this:  Code.USFmt2Decimal(Fields!InvoiceTotal.Value ) & " " & Fields!CurrencyCode.Value

Need some help on how to write this
