RMI Signal

[GeorgSpirakos@xxxxxxxxxxx (Georg Spirakos)]

Hallo  omega list,
can you help me by the signal below:

Inputs: Param1(5), Param2(13), Param3(5), Param4(13), Level1(50),
Level2(50);


If Currentbar > 1 AND RMI(Close, Param1, Param2) Cross Over Level1 Then
 Buy ("RMI_Long") next Bar on Open;

If Currentbar > 1 AND RMI(Close, Param3, Param4) Cross Below Level2 Then
 Sell ("RMI_Short") next Bar on Open;


I cannot verify it. I get the error:
Too many inputs supplied.
Thank you
Georg
