Error

[tobitba]

Hi! I´m tring to use this arduino library and Im having some issues with it. When I try to use the playVoice comand i get this error "cannot call member function 'void WTV020SD16P::playVoice(unsigned int)' without object".
I´m new at programing so I´m probably missing some lines in the code, but I dont know how I could make it work.
This is my code `#include <WTV020SD16P.h>

WTV020SD16P::WTV020SD16P(int clockPin,int dataPin,int busyPin);
void playVoice(unsigned int voiceNumber);
void setup() {
// put your setup code here, to run once:

}

void loop() {
// put your main code here, to run repeatedly:
WTV020SD16P::playVoice(1);
}
}
}`
Thanks!
