DTMF struggles

hey guys i have been trying to implement DTMf functionality for my voice agent but it seems to not work .

I got some tips from this developer call with nico,CallSense

Any help will be much appreciated,

here is the second havascript block,// Ensure tmpCode exists
tmpCode = tmpCode "";

// 1⃣ User SPOKE the digits (rare but possible)
if (last_event.type === "intent" && last_event.payload?.query) {

const spoken = String(last_event.payload.query).toLowerCase();

// convert spoken words to digits
if (spoken.includes("zero")) tmpCode += "0";
if (spoken.includes("one") spoken.includes("1")) tmpCode += "1";
if (spoken.includes("two") spoken.includes("2")) tmpCode += "2";
if (spoken.includes("three") spoken.includes("3")) tmpCode += "3";
if (spoken.includes("four") spoken.includes("4")) tmpCode += "4";
if (spoken.includes("five") spoken.includes("5")) tmpCode += "5";
if (spoken.includes("six") spoken.includes("6")) tmpCode += "6";
if (spoken.includes("seven") spoken.includes("7")) tmpCode += "7";
if (spoken.includes("eight") spoken.includes("8")) tmpCode += "8";
if (spoken.includes("nine") spoken.includes("9")) tmpCode += "9";

}

// 2⃣ User PRESSED a DTMF key
else if (last_event.type === "dtmf" && last_event.data) {

const digit = String(last_event.data);

if (!isNaN(digit)) {
tmpCode += digit;
}

}

// 3⃣ Not speech & not DTMF → reset
else {
tmpCode = "";
throw "invalid";
}


// 4⃣ When user enters 4 digits → verify
if (tmpCode.length === 4) {

if (tmpCode === randomCode) {
tmpCode = "";
return "Verified";

} else {
tmpCode = "";
return "Wrong code";
}
}

// 5⃣ Return nothing until 4 digits
return;
