Go convert reflect.Value from string to int

I am getting an error like this

reflect.Value.Convert: value of type string cannot be converted to type int
goroutine 6

When I am running this code

param := "string" // type string
ps := fn.In(i) // type int

if !reflect.TypeOf(param).ConvertibleTo(ps) {
    fmt.Print("Could not convert parameter.\n") // this is printed
}
convertedParam := reflect.ValueOf(param).Convert(ps)

Can I do this in some way without calling a switch/case?
