How do I enter a Menu choice in a statement

I am creating a program that prompts a user to choose a choice from a menu and then use that option to insert in an "fprintf" Statement. Here is what I have so far, but as you can see in the bold statement below, it is missing the choice that was chosen by the user in the beginning.

clear
clc
close all

Materials={'Ash';'Hickory';'Maple';'Pine'};

Cost=[4.35 4.95 6.35 3.75]; % Estimated material cost to produce 25 bats from each material chosen

LECost=1.25; % Labor and Energy Cost regardless of material chosen.

BatMat= menu('Please select Bat material', Materials(1), Materials(2), Materials(3), Materials(4));

if BatMat == 1;

fprintf('Ash');

elseif BatMat ==2;

fprintf('Hickory');

elseif BatMat ==3;

fprintf('Maple');

else

fprintf('Pine');

end

BatPrice=input('Please enter selling price per bat of chosen material: $');

NoBats=input('Please enter the total number of bats the manufacturer can produce per week without an upgrade: ');

NoWeeks=input('Please enter the the number of weeks the manufacturer plans to run the bat production machinery in a year: ');

%Calculation

Ttlbats= (NoBats*NoWeeks);

input('Please enter number of ADDITIONAL bats that can be produced in a week with an upgrade: ');

Fixedcost=input('Please enter the fixed cost for the upgrade: $');

VariableCost=(Cost(1)+LECost);

fprintf('Selling price per bat:\t $%0.2f \n', BatPrice);

fprintf('Total Variable Cost per bat: \t $%0.2f \n', VariableCost);

fprintf('NO UPGRADE \n');

profit=(NoBats*BatPrice);

fprintf('Producing %0.0f _%s_ bats a week for %0.0f weeks = %0.0f total bats\n\t Profit \t\t$%0.0f\n' ,NoBats,BatMat,NoWeeks,Ttlbats,profit)   %this line was marked

Your code

BatMat= menu('Please select Bat material', Materials(1), Materials(2), Materials(3), Materials(4));

if BatMat == 1;

shows us that you know that the result of menu() is the item index. But

fprintf('Producing %0.0f _%s_ bats a week for %0.0f weeks = %0.0f total bats\n\t Profit \t\t$%0.0f\n' ,NoBats,BatMat,NoWeeks,Ttlbats,profit)   %this line was marked

shows us that you now expect BatMat (the index) to be the string.

On that line you need to change BatMat to materials{BatMat}

I ended up taking out the if statements and changed the line to materials{BatMat}, which worked perfectly! Thank you!
