Why am I getting this error "Can't Assign To Array" for this code?

Dim myArray(0 To 5) As Single
Dim Var as Single

ERROR = myArray = Array(var1, var2, var3, var4, var5, var6)

For Each Var In myArray
Var = 0
Next Var

but if I code it this way everything works:

Dim myArray As Variant
Dim Var as Variant

ERROR = myArray = Array(var1, var2, var3, var4, var5, var6)

For Each Var In myArray
Var = 0
Next Var

Any help would be great.
