I had an 2 dimension array, (1 to 406, 1 to 8)
when I try to redim and perserve the value
ReDim Preserve arr(1 To UBound(arr()) + 1, 1 To 8)
it pop out error Subscript out of range, what actually Im doing wrong?
You can only ReDim Preserve the last dimension in a multidimensional array with VBA, which is a great feature.
There are some workarounds to this issue described in this answer.
