Redim Array Function With Pre-Dimensioned Arrays?

I've written this function to re-dimension an array based on the size of the range it is storing. Originally all my variables were simply declared as:

Code:

Dim XLRecOutput() as Variant

I then wrote a function which took the variable and the range as follows:

Code:

Function LoadRangeToArray(dataArray() As Variant, selectedRange As Range, Optional blnLoadData As Boolean = True)
With selectedRange
ReDim dataArray(1 To .Rows.Count, 1 To .Columns.Count)
End With
If blnLoadData Then dataArray = selectedRange
LoadRangeToArray = dataArray
End Function

To call the function, it's simply:

Code:
XLRecOutput = LoadRangeToArray(XLRecOutput, Range("XLRecOutput"))

Now I've created a class and set up Get/Let properties for the variables instead, but the above function fails with a Compile error on the call - 'Type mismatch: array or user-defined type expected' and I can't get my head around how to resolve it.
