I have a text type which hold multiple value (NE, SE, MW, NW, SW). i am using be

As Sathya indicates the fact that the index function is returning the same as the input indicates one of two things:

1. Your process variable is not marked as multiple
2. The content of the variable is not an array but a single text
---> 2.1 This is how a text array is provided ={"NE", "SE","MW", "NW", "SW"}
---->2.1 Or if passed through the UI
NE; SE,MW, NW; SW

You can actually prove this theory by using the split function:

=index(split(pv!selectedCustomerIdentifier,";"),2,1)

or, if the values are coma separated:

=index(split(pv!selectedCustomerIdentifier,","),2,1)
