Code will not compile when changing method name in related class

Question

Hello all! I'm wondering if anyone can help a second-time poster. I have a class called Transcription which holds the artist name and song title of a guitar transcription. Transcription has a method toString() which returns a String containing the artist name and title. I have a class GuitarMag which holds a vector of Transcription objects, and has a method WriteGuitarMag() which returns a String containing, among other things, the toString() method for each Transcription in the transcriptions vector. I wanted to change the method name in Transcription to writeTranscription() for consistency, but when I refer to that method in WriteGuitarMag(), GuitarMag gives an error to the effect that the writeTranscription() method does not exist.
This works fine:
    //Transcription object
    public String toString(){
        return "" + artistName + "\t\t" +  songName;
    //GuitarMag object
    public String WriteGuitarMag() {
        StringBuffer tmp1 = new StringBuffer();
        //find out how many components are in the vector
        int transCount = this.transcriptions.size();
        StringBuffer tmp = new StringBuffer("Name: " + this.getMagName() + "\n" +
               "Cover: " + this.getCoverDesc() + "\n" +
               "Date: " + this.getMagDate() + "\n" +
               "Transcriptions:" + "\n");
        for (int i = 0; i < transCount; i++) {
            tmp1.append(this.transcriptions.elementAt(i).toString() + "\n");
        tmp.append(tmp1);
        return tmp.toString();
    }But this does not:
    //Transcription object
    public String writeTranscription(){
        return "" + artistName + "\t\t" +  songName;
    //GuitarMag object
    public String WriteGuitarMag() {
        StringBuffer tmp1 = new StringBuffer();
        //find out how many components are in the vector
        int transCount = this.transcriptions.size();
        StringBuffer tmp = new StringBuffer("Name: " + this.getMagName() + "\n" +
               "Cover: " + this.getCoverDesc() + "\n" +
               "Date: " + this.getMagDate() + "\n" +
               "Transcriptions:" + "\n");
        for (int i = 0; i < transCount; i++) {
            tmp1.append(this.transcriptions.elementAt(i).writeTranscription() + "\n");
        tmp.append(tmp1);
        return tmp.toString();
    }Any thoughts or feelings about this?

Thanks for your reply. Yes, I compiled the Transcription class first, and then the GuitarMag class, so it shouldn't have been a problem. In thinking about it more today, I'm wondering if I need to cast the vector component to a Transcription object first. Because all objects have the toString() method, it works without casting, but if I rename the method it doesn't?
