Returning Correct Cell with Variable Information

[Needshelp]

I need some help here. I currently have a table with 5 products ("Inserts" 1 through 5) in the columns, and the corresponding volume and weight of each of the different 5 inserts in the rows. The volume and weight of each insert is completely variable based on inputs put in by the user on another worksheet, and there is no relationship between the weight and volume (hopefully the table will post correctly).
1 Insert 2 Inserts 3 Inserts 4 Inserts 5 Inserts
Weight 0.081926457 0.109235277 0.250899776 0.051204036 0.150198505
Volume 75000 765445 1121151.667 1121151.667 1121151.667
Total 6144.484312 83613.59634 281296.7021 57407.49023 168395.3047
% of Total 0.010294724 0.140090 0.47129619 0.096182896 0.282136494

I need a way to sort this data in another table by volume, and have the corresponding weight be sorted with the volume. This must be done automatically without the user needing to go in and sort by hand. Currently I sort the volume by using the LARGE function and then pull the correct weight by using a long IF statement (IF(the sorted cell)=(1st cell from original table),(corresponding weight), IF(the sorted cell)=(2nd cell from original table),(corresponding weight), etc.
The problem is if the volumes for 2+ of the inserts are the same, it will return the weight from the first insert at that volume, for each of the inserts with that volume (if 3 inserts have the same volume, it will return the weight of one insert for all 3 inserts at that volume) instead of giving me the weight that corresponds to each particular insert.
Any ideas? Since the weight and volume can change I can't reference a particular cell. I'm in a huge jam here so any help would be GREAT! Thanks in advance!

Welcome to the forum.

Post a workbook and explain in context.

Here's the table from my problem. Unfortunately I cannot upload the full working spreadsheet due to privacy issues, however please keep in mind that the weights and volumes do not stay constant and are continually changed in another worksheet. You can see that there are 3 different inserts with the same volume but different weights (in table at left). However the table at right which should be displaying the weights for each insert, displays the weight of the first insert at that volume for each of the three inserts.

Among equal volumes, in what order should weights appear?

To put another way, what would be the secondary sort criteria?

[Needshelp]

Among inserts with the same volume the order the weights appear does not matter. They just all need to be there.

Something like this?

IT LOOKS LIKE IT WORKS!!! Thank you for the help. I've been pulling my hair out for the past 3 days, and was about to give up on a project I've dropped about 80 hours into, because I could not find a work around. You saved my butt!!! Thanks again!!!
