How to fix Incorrect Code

Hi, my code is not giving me a valid output, but I am new to MatLab and am unsure how to fix it. The output I require is a voltage range given the input values shown.

LDR1 = input('smallest specified resistance value');
LRD2 = input('largest specified resistance value');
R1 = input ('resistance calculated from Code 2');
V = 5

function V1
V1 = V*R1/(R1+LDR1);
end

function V2
V2 = V*R1/(R1+LDR2);
end

Volt_Range = [V2 V1];

Help would be greatly appreciated.
