Hi Steve

Thanks a lot for sending to me the link to ScriptRepository.

I can access to tags such as (0020,0010) to (300a,000c), but unfortunately I can not read tags that are located in **item** , such as (300a,012c), highlighted in the following figure.

The following figure is screenshot of DICOM File Browser and the tag that I want to access its value (300a,012c).

I enter the following commands:  
\>\>\> patientList=db.patients()  
\>\>\> studyList=db.studiesForPatient(patientList[0])  
\>\>\> seriesList=db.seriesForStudy(studyList[0])  
\>\>\> fileList=db.filesForSeries(seriesList[0])  
\>\>\> print(db.fileValue(fileList[0],‘300a,000c’))  
PATIENT  
\>\>\> print(db.fileValue(fileList[0],‘300a,012c’))

```
>>>

```

As you see, the last command dose not give any output.  
Please guide me to access tags that are loacted in **Items**.  
Thanks a lot.  
Shahrokh.
