i am working on Ektron[8.60] and a beginner in it, i need to add a smart form with xslt rendering, i have made a smart form under 

```
settings> configuration> smart form configurations.

```

Now i clicked on smart form and from above toolbar clicked on edit, here i want to give the path of xslt file , but i don't know what to write here. I tried some path and it says error.

The other thing i want to know that why there are 3 radio buttons like xslt 1, xslt 2 and xslt 3 ? One xslt file is not sufficient ? 

Any help or useful link from someone.
Thanks in advance.
