Fixed role bug where enumeration was wrong

[okhleif-IL]

Description

in the loop on line 906, the variable i was in the wrong block and therefore it would never equal to a value greater than 0. This caused role to never be concatenated to the prompt string later on.

It looks like there is some extra whitespace in line 906. The linter may not like that.
