Error in Syntax for Modulus of Elasticity

Dear Readers and Moderators of COMSOL,
Hello everyone.
I am using COMSOL 4.a and 4 studying some hygro swelling studies on a particular material.
The syntax on modulus of elasticity ,E, that i would like to input is:
E (MPa) = 0.786T^2 -62.61T+1261
However i encountered so error in inputting the right syntax.
I would like to brought this matter because I don't know how to properly input the proper syntax of the modulus of elasticity as a function of temperature.
I have tried inputting the same syntax shown below into the material property as:
E(0.786T*T-62.61T+1261)[K][MPa]
I just copied this method of inputing the syntax based on the COMSOL tutorial on transient ELBOW BRACKET but COMSOL would recognize it as error.
Please teach me how to input this syntax properly.
I appreciate much if somebody could help me get this right.
Thank you so much in advance.
Jonathan

Hi
if you define E as a function (V4) as
(0.786*(T[1/K])^2 - 62.61*T[1/K] + 1261)*1[MPa]
it should do
the T[1/K] set the operand to unitless, and the *1[MPa] sets the units of the function results

Good luck
