You work as an Office Assistant for Tech Perfect Inc. You are working in a spreadsheet. You observe that while trying to look up or match a lookup_value within an array, Excel is not able to recognize the matching value. Which of the following are the reasons that are causing the above problem?

Each correct answer represents a complete solution. Choose all that apply.

A. The lookup_value or the array you are searching resides in a cell containing unseen spaces at the start or end of that cell.
B. The contents of the cells that are being compared may have different data types.
C. Excel is trying to reference an invalid cell.
D. You are inserting a new column, next to a column that is already formatted as text.

Answer: A,B 
Explanation: 
The Failure to Look Up Values in Excel error occurs when a user gets an unexpected error while trying to look up or match a lookup_value within an array and Excel is not able to recognize the matching value. If the lookup_value or the array the user is searching resides in a cell, the user can have unseen spaces at the start or end of that cell. This will create the situation where the contents of the two cells that the user is comparing look the same but extra spaces in one of the cells cause the cells to have slightly different content. The other reason is that the contents of the cells that are being compared may have different data types. Answer option C is incorrect. The Lookup Function Won't Copy Down to Other Rows error occurs when a user uses a function in one cell and it works perfectly but when he attempts to copy the function down to other rows, he gets the #REF error. The #REF!
error arises when Excel tries to reference an invalid cell. This error occurs if the user has referenced an entire worksheet by clicking on the grey square at the top left of the worksheet. For Excel, this reference range is 1 to 1048576. Since the references are Relative References, Excel automatically increases the row references when this cell is copied down to other rows in the spreadsheet. Answer option D is incorrect. The Excel Won't Calculate My Function error occurs when a user types in a function and presses Enter, the cell shows the function as the user typed it, instead of returning the function's value. The reason that causes this problem is that the cells containing the formula are formatted as 'text' instead of the 'General' type. This happens when the user inserts a new column, next to a column that is already formatted as text due to which the new column inherits the formatting of the adjacent column.
