I was running successfully crystal reports on my system but from the last few days it is throwing the following error: I have no idea how to resolve this issue? Any help?
Crystal report windows forms viewer This field name is not known. Details: errorKind Error in file ExecutiveSummary {0F273B2C-FADD-492C-B75E-9B5604AD4587}.rpt: Error in formula TolalDevices: This field name is not known. Details: errorKind
Dear Vincent Dudler,
Crystal Reports may show this error if Crystal Reports knows that it is working with a value which is not numbered. There are many conversion functions found in Crystal like CDBL, CSTR, etc., and data check functions IsNull, IsNumeric, etc., which can be used.
If you want to get rid of this problem, you have to convert the value to DBL and it will solve your problem.
Thank you,
Lesliez Mark
