Forms :: 9i Form To Load Attendance Data

I want to use SQLLDR (sql loader) in my forms9i form to load attendance data therefore I installed SQLLDR utility in user computer but it is not working,

Begin
:message := 'Please Wait, Data LOADING...!';
Delete From atnd_load;
Forms_ddl('Commit');
utlt:= 'c:oracleora90insqlldr';
usr:= 'vikorapp';
pass := 'vikorapp';
strng := 'laptop';
cntrl := 'C:VikorPayrollFormsAtndCtl.ctl';
lg := 'c: empAtndLog.log';
bad := 'c: empAtndBad.bad';
host(cmd);
:message:= 'Data Loading Complete...!';
End;
