Invalid expression. When calling a function or indexing a variable, use parentheses. Otherwise, check for mismatched delimiters. Can anyone help in this error?

Ran in:
M = 1:10;
R = 200:300;
Mean = mean(M);
Range = mean(R)
Range = 250
d = 2.326;
n = 5;
SE = Range./(d*sqrt(n)) % check the parenthesis and [ ] is used for concatenating numbers /arrays
SE = 48.0668
