error with allocation of gsigout

When using the Usrdef_Time_Series routine I want to output also the bed_fraction. This is in the domain_type ='S' - so not a variable in the water column but in the sea bottom. When I output this in one file, either on a grid (GRIDDED output) or for different stations (GRIDDED = false) there are no problems. However when I want to output both of them, so adding two sets and opening two different files for the gridded output and the output at stations, there is a problem. The gsigout variable cannot be allocated. I suppose it is a problem that the program does not want to allocate this variable again. However there are no problems to output one variable in the domain_type = 'W' both in the gridded output and for stations. So there this problem is solved.

Thanks for your suggestions.
