I run analysis and get following error message:
ERROR 131 : The following links form cyclic loops in the drainage system.
Analysis began on: Thu Jul 17 06:56:36 2014
Analysis ended on: Thu Jul 17 06:56:36 2014
Total elapsed time: < 1 sec
There is no listing of links that form the loops.
????????????????
Did you read in the Help Manual about ERROR 131? It is probably located in the manual somewhere between pages 90-100.
