Ahora me surge otro error >.>
Lo cambie por:
Cita: $montito = "UPDATE tecnopoints SET $row_dat[tp] = '$yu' WHERE usuario = '$_SESSION[MM_Username]'";
$banqi = "UPDATE banco SET $row_banco[tp] = '$ya' WHERE usuario = '$_SESSION[MM_Username]'";
Y me dice:
Cita: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '9223372036854775807 = '9223372036854775807' WHERE usuario = 'lauchu'' at line 1
