You call us a function and the reality says you think that's your problem

 <input type="button" name="" value="enviar" onclick="usu()"/>

You have a problem in this line, the comma at the end is not going

$sql= "INSERT INTO ventas_Cuentas(cuenta,folio,cliente)VALUES(999,292,'.$usu.',)";

It should be like this

$sql= "INSERT INTO ventas_Cuentas(cuenta,folio,cliente)VALUES(999,292,'.$usu.')";
