Using INDIRECT Function To Create Custom Validation

I have a worksheet that uses the INDIRECT function as part of cell validation to generate a custom 'name' range, this name then references a bunch of sheets that contain the actual range where the values for the validation list are stored. For example: ValidationExample.xlsx

Name = Color
Values = Blue, Red, Green

Name = Shape
Values = Square, Circle, Triangle

So what this allows me to do is in the first cell, I can define two options such as Color and Shape. Once one of these is selected, the next cell will have a formula for the validation as "=INDIRECT(A1)" then I will define two named ranges called 'Color' and 'Shape'. This will then show me the list of items in the cell based on previous selection. An example of this is attached to this posting above.

When the formula is written into the validation, an error message is generated saying that the formula will generate an error. Even with this message, the method works effectively to provide a blank list if nothing in the first cell is selected, or a list dependent on the selection of the first cell.

In this case, what I want to do is generate a macro that will populate the validation for a cell when new records are added. This won't always copy down from previous cells because the way I add records is through use of a macro and I generally find using the format painter in vba to be a fairly sloppy way of getting formats from other cells. So I go through a series of validation additions to each cell in the worksheet to get this validation created (I have no written this into the workbook attached).

VB:
Dim i As Long
Dim lastRow As Long
Dim sht As worksheet

[Code] .....

As I read in previous posts, Formula1 cannot contain an actual formula, only names and lists of items. Since each of the cells will have a changing reference, thus the INDIRECT function would need to change to reflect this, The 'Secondary' name consists of the following:

"=INDIRECT(OFFSET(INDIRECT(ADDRESS(ROW(), COLUMN()), 0,-1)))"

Which of course does not work due to the error when using INDIRECT in the first place (though the Address() function appropriately finds the cell with the validation in it's appropriate address). I can think of other ways to do this, such as having validation lists change in with VBA on a SelectionChange or Change event, but that's a lot of code that is subject to change when the named ranges have changes to them (which is fairly frequent). Is there any way to get the .Validation.Add method to ignore errors in the name supplied to it.

For reference, my code is this:

VB:
Private Sub cmdRefreshValidation_Click()
'Re-enters validation parameters to all cells to allow selections
Dim i As Long
Dim lastRow As Long
Dim sht As Worksheet
