Retrieving ZULU TIME results in a black screen

So what on earth did I do wrong?double getZuluHour(double temp){ double tmp=0; execute_calculator_code("(E:ZULU TIME, seconds)",&tmp,NULL,NULL); tmp=tmp/3600; return tmp;}//------------------- double time=0; time=getZuluHour(time); sprintf(pelement->string, "%12s%s", "Zulu hour = ",time);Oddly enough, I had the same problem when trying to retrieve ELAPSED_SECONDS via the C interface. Any attempt to display elapsedsecs.var_value.n also resulted in a black screen. Can anyone shed any light on this please?-DaiOkay - stupid here just spotted the problem. Doubles ain't strings.....-Dai
