Using interpolation to define temperature-dependent material properties

Hi,

I am a COMSOL beginner. Trying to added a file containing temperatures and measured material properties and then utilize an interpolation function to define the temperature-dependent material properties. I have attached both the COMSOL file and the material property file. The first and third columns contain the temperatures and the 2nd and 4th columns are the corresponding measured properties. (I've attached the 'xlsx' file as I couldn't attached the 'csv' file I used in the model)

Any advice will be appreciated. Perhaps there already exist examples that I can follow to complete my model.

Thanks in advance.
