PDE TOOLBOOX heat transfer error

Why am I getting this error??? I want to observe conduction heat transfer on Stacked Cylindricall Cells. I keep getting the same error;

Check for missing argument or incorrect argument data type in call to function 'thermalProperties'.

Error in bugnshaf (line 26) ''thermalProperties(modelc,'ThermalConductivity',k,'SpecificHeat',Cp,'MassDensity',rho)''

My codes

modelc = createpde('thermal','transient');

modelc = createpde

gm = multicylinder(0.28,[0.724 0.802 0.702 3.353],'ZOffset',[0 0.724 1.526 2.228])

modelc.Geometry = gm

pdegplot(modelc,'CellLabels','on','FaceAlpha',0.99)

subplot(1,2,2)

pdegplot(model,'FaceAlpha',0.25,'FaceLabel','on')

You are overwriting modelc immediately after creating the thermal model. Remove the second line: modelc = createpde

[Muslu Suduragi]

Thank you. But still the error persists

[Ravi Kumar]

What is the error you are getting now?

[Ravi Kumar]

I ran your code after removing the line I mentioned and got the following result. No error.
