This is what I have so far, having trouble adding user input into a row vector the same amount of times as for loop

score =inputdlg('Please enter a number of scores between 1 and 10:\n'); % Prompt and Get a score input
data = str2double(score);
x = [];
if 1<= data && 10>=data
    for i = 1 < score
        x(end+1) = input('Input a number: ');
    end
else
    errordlg('Wrong Input')
end

 %if true
   for i = 1 : data
        x(i) = input('Input a number: ');
    end

Change the for loop structure as above

Try using the data. variable

it works

for i = 1 : data
        x(i) = input('Input a number: ');
end

Look up for in the documentation ... replace

for i = 1 < score

by

for i = 1 : data

When I tired to run it making the correct changes this is what I got

Operator ':' is not supported for operands of type 'cell'.

Any clue as to why?

The operator ':' appears in the for-statement and the value of the variable, data, should be double. That error should not occur. Did you really use the for-statement

for i = 1 : data

If you did, run

whos data

and show me the output
