How to get position of '/' in a text using glidefunction:position() and then use it in substring

[ghulesanket]

Hi,

I want to get the position of '/' in a text using the glidefunction:position().And then want to use it in substring.

Tried to escape the value but it returns error/garbage value. I cannot use other javascript functions because only basic functions are included in reports.

Code:

glidefunction:substring(category,'0',position('/',category))

Eg. I have string - 'Network Services / VPN / Cloud'

       So after the code execution I want to display only - 'Network Services'

How can we do this ? Thanks in Advance
