1. Formula: \[ =VLOOKUP(B1, B4 : D6, 2, 0) \]
Reason: The reference range used in this formula (B4:D6) does not include the entire data set. The range should start from the top row of the table (e.g., B1:D7) for proper referencing.
2. Formula: \[ =SQRT(VLOOKUP(C2, C2 : D8, 2, 0) - 100) \]
Reason: The VLOOKUP function is trying to search for the value in C2 within the range C2:D8, which results in an invalid range. The lookup value should exist within a different range.
3. Formula: \[ =VLOOKUP(B5, B6 : D8, 1, 0) \]
Reason: The 1st column index (A) does not exist in the lookup range (B6:D8). The first column should be in the lookup range for the formula to work properly.
4. Formula: \[ =VLOOKUP(B3, B2 : D5, 5, 0) \]
Reason: The column index (5) exceeds the available columns in the specified range (B2:D5). The column index should be less than or equal to the number of columns in the range.
5. Formula: \[ =VLOOKUP(B5, B3 : D8, 0) \]
Reason: The column index (0) is invalid. The column index must be a positive integer that corresponds to a column number within the given range.
6. Formula: \[ =VLOOKUP(B2, B2 : D7, 2, 0) \]
Reason: This error occurs if the lookup value (B2) does not exist in the first column of the specified range. Ensure the lookup value is available in the range for a correct lookup.
