I am absolutely desperate to figure this out.

I have an Excel spreadsheet with a column of part numbers numbers
(alphanumeric).

We use an inventory management program that is located on a Citrix server.
All I am trying to do is communicate with this program via an Excel macro.

I know this is a vague question, but I can provide specifics as needed.
Please let me know if any of you have any experience communicating from Excel
to a program on a citrx server, or if this is even possible. Thanks.
