Problem simulating NTC on Multisim12

[Theis123]

I need to create a temperature sensor using a NTC termistor for a class, using VCC = 15V. Making the calculations with R(T) = Ro*EXP(B*((1/T) - (1/TO))), Where TO = 25°C, Ro = 10k and B = 4000. Making R (T) paralel with a Rp = 7.5k and the equivalent Req in serie with a Rs = 270, i should be getting 1.51V, but when I simulate it, I get 15V. Can anybody help me out on why this is happening

The sensor model no description TEMP function
