I have calculated costs from each floor but now I need to calculate total cost for all floors how would I do this?

This code all works but Im not sure how to combine each floors total cost to get the overall building cost.(Im sorry its long.)

choice9 = questdlg('Would you like to calculate costs for spaces?','question','yes','no','yes');
switch choice9
    case 'no'
        disp('not calculating cost')
    case 'yes'
        
        ResidentialCost=input('Please enter the building cost for residential spaces per m^2: ');
        OfficeCost=input('Please enter the building cost for office spaces per m^2: ');
        EducationalCost=input('Please enter the building cost for educational spaces per m^2: ');
        ToiletCost=input('Please enter the building cost for toilet spaces per m^2: ');
        StorageCost=input('Please enter the building cost for Storage spaces per m^2: ');
        if ResidentialArea<=0 || ResidentialCost<=0
            TotalResidentialCost=0;
            disp('No cost for residential spaces')
        else
            TotalResidentialCost= ResidentialCost*ResidentialArea;
            disp("Your total cost for floor "+c+" residential spaces is:"+TotalResidentialCost)
        end
        if OfficeArea<=0 || OfficeCost<=0
            TotalOfficeCost=0;
            disp('No cost for office spaces')
        else
            TotalOfficeCost= OfficeCost*OfficeArea;
            disp("Your total cost for floor "+c+" office spaces is:"+TotalOfficeCost)
        end
        if EducationalArea<=0 || EducationalCost<=0
            TotalEducationalCost=0;
            disp('No cost for educational spaces')
        else
            TotalEducationalCost= EducationalCost*EducationalArea;
            disp("Your total cost for floor "+c+" educational spaces is:"+TotalEducationalCost)
        end
        if ToiletArea<=0 || ToiletCost<=0
            TotalToiletCost=0;
            disp('No cost for educational spaces')
        else
            TotalToiletCost= ToiletCost*ToiletArea;
            disp("Your total cost for floor "+c+" toilet spaces is:"+TotalToiletCost)
        end
        if StorageArea<=0 || StorageCost<=0
            TotalStorageCost=0;
            disp('No cost for storage spaces:')
        else
            TotalStorageCost= StorageCost*StorageArea;
            disp("Your total cost for floor "+c+" storage spaces is:"+TotalStorageCost)
        end
        OverallCost=0;
        OverallCost=TotalStorageCost+TotalToiletCost+TotalEducationalCost+TotalOfficeCost+TotalResidentialCost+OverallCost;
        disp("Your running total for floor "+c+" is: "+OverallCost)
end
end

It is hard to tell without seeing the rest of the code but I believe you can use a variable to store the total cost of floors from 1 to c outside the loop and keep adding the overall floor cost to it.

% I assume there is some way to input the number of floors and areas for
% each floor but I just used sample values here.
nFloors = 3;
RunningBuildingCost = 0;
for c = 1:nFloors
    ResidentialArea = 1; 
    OfficeArea =1;
    EducationalArea = 1;
    ToiletArea = 1;
    StorageArea = 1;
