Respuesta :
There is most likely an error with the formula, causing it to be unable to auto complete.
Answer:
The AutoComplete feature is not working because it only works with text.
Explanation:
AutoComplete is a feature that analyzes what you are typing and fills in automatically the text. You will have to write the first letters and Excel will review if what you wrote match another cell and will complete the words. This feature only works with text, so if you are entering numbers, it will not complete automatically what you are writing.
