VBA set sheet based on sheet Array and Part of Cell Value Array

[decadence]

Hi, My Code below is so I can get the cell value from the lookup workbook and add it to the Active Workbook if both cells values are the same

What I would like to do is match part of a cell value to a sheet name and set that sheet as the look up sheet.

Each part of a cell value will vary but will always have the same prefix before an underscore in every cell of a Range, so I would like to use the underscore to find the prefix. Each Sheet will have the a prefix as it's name in the lookup workbook.

So what I want to do is match the cell prefix from the Active Sheet to the sheet name prefix from the lookup workbook and set that sheet prefix as the lookup sheet if the cell prefix is found so I can get the value from the prefix sheet and add it to the Active Sheet.


Example 1

IPN	Customer Part
APPLE01_123456
APPLE01_987654

<tbody>
</tbody>

Example 2

VPN	Customer Part
BANANA_654321
BANANA_139756

<tbody>
</tbody>
