Using Consolidate function with an array of Ranges

Here's a simple example of a use of the Consolidate method that works for me. Hopefully, this will work on your side and help you see what isn't working, but if it doesn't we'll know that it's not your code that is at fault.

First add the following to Sheet1:

And the following in Sheet2:

Then make sure that Sheet3 is empty and run the following (from a module in the same workbook):

Sub ConsolidateTest()

    Dim rng As Range
    Set rng = ThisWorkbook.Sheets("Sheet3").Cells(1, 1)
       
    rng.Consolidate _
        Sources:=Array("Sheet1!R1C1:R3C3", "Sheet2!R1C1:R3C3"), _
        Function:=-4157, _
        TopRow:=True, _
        LeftColumn:=True, _
        CreateLinks:=False

End Sub

You should then get the following result:

Thanks for the help guys, sorry about my slow response. In the end I gave up on the built in consolidate function and just made my own. It loops through the combined table that I made just to check that my loop function was working, checks if the first column matches and if it does it sums the 8th columnn, then deletes the original row. The tables I were working with all had the same number of columns, but could be different numbers of rows, some worksheets had multiple tables on them, and no matter how I tried to use the consolidate function it just didn't seem to want to work the same as when you use the Consolidation button under Data in excel.

You can find all of my code below, I have been a bit lazy in commenting out the superfluous code but since I got it working I walked away from it a bit without tidying it up. So if you are ever looking for a way to create a checkbox list for each table you have in a workbook, then combine certain tables and consolidate them, this may help you. The code is a bit of a mess and I'm sure there are more efficient ways of doing what I have done but this way worked for me. I did copy some code from various places, and where I did I tried to leave the comments in.
