i have four tables with four dataset : dataset1, dataset2, dataset3, dataset4
this expression is present in the table with dataset 4 besides the field ID.
=First(Fields!VIEWERURL.Value, "DataSet3") + "?userName=" +First(Fields!USERVALUE.Value, "DataSet1") + "&orgid=" + First(Fields!ORGID.Value, "DataSet2")+ "&ID=" + Fields!_ID.Value
it works till here but once i add the ID field it gives the error
=First(Fields!VIEWERURL.Value, "DataSet3") + "?userName=" +First(Fields!USERVALUE.Value, "DataSet1") + "&orgid=" + First(Fields!ORGID.Value, "DataSet2")+ "&ID="
Any suggestion
