I'm not sure I know what you mean. Do you mean I should expand my survey by adding more notes with subsequent signArea labels?
Like this?
note signArea Sign Area: if(selected(${signtype},'R1-1 - Stop'),((1 + sqrt(2)) * 2) * (pow((${widthnote} div 12), 2) div 2.4), 0)
note signArea Sign Area: if(selected(${signtype},'M1-7 - NFS ROUTE MARKER' or 'M1-6 - County Route Sign (1 - 3 digits)'),pow((${heightnote} div 12), 2) * 0.76, 0)
note signArea Sign Area: if(selected(${signtype},'R1-2 - Yield 36x36' or 'R1-2 - Yield (Low Volume Roads)'),${heightnote} * ${heightnote} div 333, 0)
note signArea Sign Area: if(selected(${signtype},'S1-1 - School' or 'SS4-5 - School Speed 15 MPH Ahead (Symbol)'),${widthnote} * ${widthnote} * 0.0052083, 0)
note signArea Sign Area: if(selected(${signtype},'T3B - Type 3 Barricade'),${widthnote} div 12, 0)
note signArea Sign Area: if(selected(${signtype},'W10-1 - Grade Crossing Advance Warning'),(${widthnote} * ${heightnote}) div 182.5, 0)
note signArea Sign Area: if(selected(${signtype},'W14-3 - No Passing Zone (Pennant)'),${heightnote} * ${heightnote} * 0.0042918, 0)
note signArea Sign Area: Max((${widthnote} * ${heightnote}) div 144)
Is that anything close to what you are suggesting? Thanks for all your help.
