Can't assign to an array

Each element of an array must have its value assigned individually. This error has the following causes and solutions:

  • You inadvertently tried to assign a single value to an array variable without specifying the element to which the value should be assigned.
To assign a single value to an array element, you must specify the element in a subscript. For example, if  `MyArray` is an integer array, the[expression ](vbe-glossary.md) ` MyArray = 5` is invalid, but the following expression is valid: `MyArray(UBound(MyArray)) = 5`
  • You tried to assign a whole array to another array.
For example, if  `Arr1` is an array and `Arr2` is another array, the following two assignments are both invalid:
Arr1 = Arr2    ' Invalid assignment. 
Arr1() = Arr2()    ' Invalid assignment. 
To assign one array to another, make sure the array on the left-hand side of the assignment is resizable and the types of the array match.

 **Note**  You can place a whole array in a  **Variant**, resulting in a single variant variable containing the whole array:
Dim MyArr As Variant 
MyVar = Arr2() 
You then reference the elements of the array in the variant with the same subscript notation as for a normal array, for example:
MyVar(3) = MyVar(1) + MyVar(5)
