Unable to save all the data in workspace, app designer

Greetings

I made the following code, using app designer, and the first part works just fine, I can save the data when the selection is ABS or PE+PP in the workspace, but related with the coolant information (Cooling_fluid), something is wrong, and so far I do not know what it is, thanks for any help

 if true
                Min_radius = app.MinradiusmmEditField.Value;
                Max_radius = app.MaxradiusmmEditField.Value;
                Material_selection = app.PartmaterialDropDown.Value;
                switch Material_selection
                    case 'ABS'
                        Material_selection =  cellstr('ABS');
                        assignin('base','Specific_heat_part',2.4);
                        assignin('base','Conductivity_part',0.18);
                        
                    case 'PE+PP'
                        Material_selection = cellstr('PE + PP');
                        assignin('base','Specific_heat_part',2.2);
                        assignin('base','Conductivity_part',0.16);
                end
                
                
                Cooling_fluid = app.CoolingChannelDropDown.Value;
                switch Cooling_fluid
                    case 'Yes'
                        Cooling_fluid = cellstr('Water');
                        assignin('base','Specific_heat_coolant',4.18);
                        assignin('base','Conductivity_coolant',5.98);
                        
                    case 'No'
                        Cooling_fluid = cellstr('None');
                        assignin('base','Specific_heat_coolant',0);
                        assignin('base','Conductivity_coolant',0);
                        
                end
                save('pathtomat.mat','Min_radius','Max_radius','Material_selection','Cooling_fluid');
            end
            Table_info = [Min_radius Max_radius Cooling_fluid Material_selection];
            app.DATA_INPUT.Data = Table_info;
            assignin('base','Min_radius',Min_radius);
            assignin('base','Max_radius',Max_radius);

Hi,

The code seems fine, can you please give more information about the issue you are facing with coolant information to help you better.
