Question : Distinct count

Good Afternoon:

Here is my question:

The data :

cr_urn                                         IN      
a123                                            1
a123                                            1
a123                                            1                          
a234                                            0                            
a234                                            0                            a234                                            0                            
a555                                            1



I want to at the end of the report to show that I have  a total of  2 inpatients .

My attempted soln for inpatient column :

IF NOT ONLASTRECORD THEN
IF {NHS_Implant_Report_sp4_test_4.cr_urn}<>NEXT({NHS_Implant_Report_sp4_test_4.cr_urn}) AND {NHS_Implant_Report_sp4_test_4.crp_status}='IN' THEN
1
ELSE
0 ;
**************this gives me

a123                      0
a123                      0    
a123                      1
a234                      0
a234                      0
a234                      0
a555                      0*** this should be one.

I am going for coffee now....I hope you can solve this one..as I know this is a basic question :-)

Thank you,
Lucy

Answer : Distinct count

Try it this way

IF NOT ONLASTRECORD THEN
    IF {NHS_Implant_Report_sp4_test_4.cr_urn}<>NEXT({NHS_Implant_Report_sp4_test_4.cr_urn}) AND  
                  {NHS_Implant_Report_sp4_test_4.crp_status}='IN' THEN
        1
   ELSE
        0
Else
 1;

The else goes with the second if so no value is returned;

You may actually need to try it this way

IF ONLASTRECORD THEN
   If ({NHS_Implant_Report_sp4_test_4.crp_status}='IN' ) then
      1
   Else
      0
Else IF {NHS_Implant_Report_sp4_test_4.cr_urn}<>NEXT({NHS_Implant_Report_sp4_test_4.cr_urn}) AND  
                  {NHS_Implant_Report_sp4_test_4.crp_status}='IN' THEN
      1
ELSE
      0
