Hi there.
If anyone finds this error with no aparently reason, because under notes client works perfectly, this is what I did find out, after many hours of tests.
My form have a numeric field with allow multi-values set, that represents an numeric array in lotusscript.
The multi-values options had to be set both to newline unless the form did not work on web browsers.
The only cue I got was this found on notes log:
HTTP Web Server: Lotus Notes Exception - Cannot convert text to a number [/WEN/chnew.nsf/f66a0ff4c0b2c18980257307005618be/d692332879fcca298025741100569a07?EditDocument&Seq=1]
Best Regards
