Section 420 IPC frame charged

in my matter order are passsed by judge against accused under section 471 ipc charges are framed and for trail but now my advocate is saying that we can also challenge court order as accused should also be framed under section 420 ipc but he is saying that if we challenge this court order judge can go against us... and also he is saying that accused can also challenge the order in court and for this procedure we have time limit of 3 months....i want help what to do further as my advocate is saying us to decide that challenge this order or wait for accused to challenge the order.. sir if accused person challenge this order then in our defence we can argue for 420 section in stead of challenging the order directly as my advocate is saying tht if we will challenge first judge can go against us as till now he is in our favour.
