non linear mapping help

okay well when I do the first code on that page I tried a 10k resistor and get a hi reading of 134000 so i when back to a 32000, I get 27333 as a thermal resistance, If I try a 32000 in the second coding I get inf.

I think its because he is using this at 3.3 using analog ref to be less noisy. Im using a pro mini inland. it doesnt have a vref or 3.3 pin. so What are my options? will this woek or do i need a board with vref and a 3.3?

I didnt that what how they set there code

I think im close the ambent value is 102000 of thermistor. Im using a 32k
