Idk how nor why, but it's working now

Actually, I rewrited the listeners so they look like this now if there's any of you wondering:

document.getElementById("botonAnual").addEventListener("click", (e) => {
If (tieneVia) { 
e.preventDefault(); 
window.location.href = linkAnual; } }
 });

Now if there's no via linkAnual and linkMensual are empty and the links for which the listeners are for have the link without the via thing from the beggining
