Issue:
A column named 'Field Name' already belongs to this DataTable: cannot set a nested table name to the same name.
Exception:
[DuplicateNameException: A column named 'Field Name' already belongs to this DataTable: cannot set a nested table name to the same name.]
System.Data.DataColumnCollection.RegisterName(String name, Object obj) +247
System.Data.DataColumn.set_ColumnName(String value) +164
Code5Systems.FormMaster.Business.FormDataController.GetDataSetFromFormResults(String xml, String modulePath, Boolean fromControl) +609
Code5Systems.FormMaster.Business.FormDataController.List(Int32 moduleId, DateTime dtStart, DateTime dtEnd, Int32 pageNum, Int32 pageSize, String modulePath, Boolean fromControl) +59
Code5Systems.FormMaster.FormReport.BindGrid() +271

Resolution:
Using the attached file
Unzip and put the file (FormResultsDataSet.xslt) in the archive in
DNNRoot/DesktopModules/Code5Systems_FormMaster/assets/xslt
Please make a backup of the file before copying over with this new one.
If all goes well the duplicated columns should get a number appended to the name, which will satisfy the DataSet Creation Process.
