Input error checking using a while loop

For part of my assignment we have to ask for a number range between .1 and 0.1 and so I wrote my code as seen below. When I run it I get the following error message from the line I underlined.

"Invalid expression. Check for missing multiplication operator, missing or unbalanced delimiters, or other syntax error. To construct matrices, use brackets instead of parentheses."

How can I make the while loop check that y is between .1 and .01

y = input('Please type in the selected accuracy (must be between .1 and .01)');

while(y>0.1 or y<0.01)

disp('Sorry, that value is not within the acceptable range');

y = input('Please input a value that is within the acceptable range');

end

y = input('Please type in the selected accuracy (must be between .1 and .01): ');
while isempty(y) || y>0.1 || y<0.01
	disp('Sorry, that value is not within the acceptable range');
	y = input('Please input a value that is within the acceptable range: ');
end
