If formula - too many functions for this argument error

Here is my formula, please help me find the error!

Formula:

=iferror(F:F="", if(and(vlookup(Database!A:F,6,false)<=Delinquency!K:K, vlookup(Delinquency!K:K,Database!A:G,7,false)*Delinquency!S:S>=Delinquency!T:T), "X", ""), if(vlookup(Delinquency!F:F,CHCs!A:F,6,false)="x", if(and(vlookup(Delinquency!B:B,Database!A:F,6,false)<=Delinquency!K:K, vlookup(Delinquency!B:B,Database!A:G,7)*Delinquency!S:S>=Delinquency!T:T),"X",""),""),""),"")

Thank you!
