You are actually importing? HOw are you importing? You're using the "import from spreadsheet" list type or something else? What happens when you perform the same action when removing Citrix from the equation? Have you done any testing
to narrow down the variables so that you know exactly which variable is causing the issue? Does the Excel file have macros? Does the error come from Excel, SharePoint, or Citrix?
So many questions that you need to answer first before we can answer anything.
