Dear list members,

I am a relatively new user of XP-SWMM , and I am having troubles using the interface files to pass the hydrographs generated in the runoff module to the extran module. It seems that the program works ok with certain numbers of subcatchments, with more catchments the program(in runoff module) gives an error message, in the other hand if I disabled the interface file , the program runs propperly but I have to print out the hydrographs and type them in to the extran module.

Thanks for your help.
