VBA Constant Expression Required
We covered arrays, static arrays and dynamic arrays in a previous tutorial. We are going to look at a common error associated with static arrays called Constant Expression Required. This error is generated when you try to use a static array instead of a dynamic array as shown in the code below:
The static array needs to have constants used to set it since it is fixed.
The way to resolve this error is to use a Dynamic array variable instead. You would use the ReDim keyword every time you want to resize the array. This is shown in the code below:
Sub UsingReDim() Dim value1 As Integer Dim value2 As Integer Dim value3 As Integer value1 = 3 value2 = 9 value3 = 15 Dim listofvalues() As Integer ReDim listofvalues(value1) End Sub
