Undefined operator '>=' for input arguments of type 'cell'.

x = inputdlg({'Pick a value between 0 and 1, and  will try my best to guess a number greater than that! '},...
    'Critical Number Guesser', [1 30]); % This line takes the user input and stores it as the variable x
if  x >= 1
    msgbox("Invalid Input", "Error", "error");
elseif x <= 0
    msgbox("Invalid Input", "Error", "error");

I keep trying to run this code, but I keep getting this error message

you can adust it to take out the cell using cell2mat() function or quick cell indexing using the curly brackets {} can do the trick. see below

x = inputdlg({'Pick a value between 0 and 1, and  will try my best to guess a number greater than that! '},...
    'Critical Number Guesser', [1 30]); % This line takes the user input and stores it as the variable x

if x{1} >= 1
    msgbox("Invalid Input", "Error", "error");
elseif x{1} <= 0
    msgbox("Invalid Input", "Error", "error");
end
