How can I link Aspen plus and matlab

Dear,
Is there any one can help me on the code that already shared about Aspen plus - MATLAB link? Since I can get access to Aspen plus V10, so I tried to link MATLAB with Aspen plus V8.8.
But when i run the code---a slightly change compared to the original code (Version and file name). Instead of running 'Reactive_Distillation.bkp', I run the file 'ETHANOLColumn_v8.8.bkp' shared for the optimisation in Aspen and MATLAB.
%% Example of Application
Reflux_Ratio = [1, 3, 5, 7];
for i = 1:length(Reflux_Ratio)
Aspen.Tree.FindNode("\Data\Blocks\T-101\Input\BASIS_RR").Value; % Column Reflux
It shows the error on the sentence 'Aspen.Tree.FindNode("\Data\Blocks\T-101\Input\BASIS_RR").Value; % Column Reflux'.
>> AspenPlus_Matlab_Link
Dot indexing is not supported for variables of this type.
Error in AspenPlus_Matlab_Link (line 17)
Aspen.Tree.FindNode("\Data\Blocks\T-101\Input\BASIS_RR").Value; % Column Reflux
Can anyone help me on this ? I can invoke the aspen file but when trying to do sensitivity analysis, the error shows on the input sentence.
Thank you so much!

Bolded text might be the error. See the documentation on FindNode function.
Aspen.Tree.FindNode("\Data\Blocks\T-101\Input\BASIS_RR").Value
Here's a link that might be of use. https://stackoverflow.com/questions/51589733/avoid-syntax-error-using-hyphens-in-python
