i have fixed my script and working very well now. without any help from anyone. i just went through each sub function to make sure each works

wat was confusing me is that. i thought i can just call only 1 function and leave others behind and run themselves on script execution

Now my mine point is to work on this script efficacy and effective to deliver msg to over 100k receivers

Anyone want to addone something, so it become more effective on delivering msg to 100k, i appreciate
