I have some Javascript, inside a <<script>><</script>>.

I keep getting the following message:

>Error: <<script>>: bad evaluation: Unexpected token '{'

I think the error is in the following lines:

let w=6;

if (svars.pattern[svars.arpeggio][1]==4) {

  let w=4;
            
} elseif (svars.pattern[svars.arpeggio][1]==6) {

  let w=3;
    
}

but I can't work out what's wrong.

$pattern is an array in the main program, and $arpeggio is a single variable in the main program.

EDITED TO ADD: Here's the entire script.

&lt;&lt;script&gt;&gt;

const svars = State.variables;
    
    let file = new Midi.File();
  
  let track = new Midi.Track();
    file.addTrack(track);
    
    track.setTimeSignature(svars.pattern[svars.arpeggio][1], svars.pattern[svars.arpeggio][2]);

track.setTempo(40);

 
    /*
    
Write the arpeggio part once.
    
    */
    
let track1 = new Midi.Track();
    file.addTrack(track1);

for (let z=1; z&lt;=svars.bars; z++) {

w=6;

        if (svars.pattern[svars.arpeggio][1]==4) {

w=4;
            
    } elseif (svars.pattern[svars.arpeggio][1]==6) {

w=3;
    
}

for (let x=1; x&lt;=4; x++) {
        
        for (let y=1; y&lt;=w; y++) {
            
if (svars.pattern[svars.arpeggio][y]==5) {
        
        track1.addNote(0, svars.chord_pitch[z][1]+12, 32);
        
                } else {
                
                track1.addNote(0, svars.chord_pitch[z][svars.pattern[svars.arpeggio][y]], 32);
                
                }

        }

}

    }

    let data = file.toBytes();
    let datarr = new Uint8Array(data.length);
    for(let i = 0; i &lt; data.length; i++) {
        datarr[i] = data[i].codePointAt();
    }
    let blob = new Blob([datarr], { type: "application/octet-stream" });
    saveAs(blob, "music.midi");

&lt;&lt;/script&gt;&gt;

I can't find the error in this Javascript.
