SharePoint Calculated Column if statements with 3 arguments

[TonyTone365]

I am stuck in writing a calculated column. Alist column has a range of blood alcohol content ranging from 0.00-0.500. I originally created this calculation:

=IF([Breath Test Result]<=0.08,"Legal Limit","Illegal Limit")

however, it only worked for 2 arguments and not accounting for the N/A selection. I then adjusted to this one:

=IF([Breath Test Result]<0.80,"Legal",IF(AND([Breath Test Result]>0.081,[Breath Test Result]<=0.500),"Illegal",IF([Breath Test Result]="n/a","no results)))

but SharePoint 365 is telling me that the syntax is wrong. Can anyone please help?

@TonyTone365 

What is the type of Breath Test Result field? is it Choice field or Number field?

[#3]

@TonyTone365 Try using below formulas and see which one works best for your requirements: 

=IF([Breath Test Result]<0.80,"Legal",IF(AND([Breath Test Result]>0.081,[Breath Test Result]<=0.500),"Illegal",IF([Breath Test Result]="N/A","No Results,"")))

OR

=IF(OR(ISBLANK([Breath Test Result]),[Breath Test Result]="N/A"),"No Results,IF(Value([Breath Test Result])<0.80,"Legal",IF(AND(Value([Breath Test Result])>0.081,Value([Breath Test Result])<=0.500),"Illegal","")))

The you for responding. The breath Test Result is a choice field... for example:
n/a
0.001
0.002
0.003
...
0.499
0.500

@ganeshsanap, I appreciate you looking into these formulas. I tried plugging in your suggestions but continue to get an error message. I am no expert in SharePoint, clearly, so I am not sure if it should be known that the "Breath Test Result" is a choice field ranging from 0.001 to 0.500. It is not a number field and don't know if it makes a difference.

@TonyTone365 I missed one double quote ( " ) in my response above, try using this formula: 

=IF(OR(ISBLANK([Breath Test Result]),[Breath Test Result]="N/A"),"No Results",IF(Value([Breath Test Result])<0.80,"Legal",IF(AND(Value([Breath Test Result])>0.081,Value([Breath Test Result])<=0.500),"Illegal","")))
