Fixing an indicator

 
Hi all,

I'm new here. I want to know if I'm allow to ask for help to fix an indicator. I found this indicator in another forum but since the developer don't want to fix it, I'm trying to fix it myself. However, because lack of experience and new to MQL4, I cannot fix it. I want to know if I am allow to post the code here.
