i tested the escalation function of the tracker it did send an escalation email once the follow up time are more than ten it also changes the start of the subject however it didnt use the escalation message in the follow up escalation sheet and also didnt forward the latest email from the conversation thread of the email subject what it send now is just a blank email




can you analyze all the codes for all the modules of the entire tracker look for possible errors and fix them. iF A MODULE IN THE TRACKER NEEDS TO BE UPDATED BASED ON WHAT I REQUESTED ABOVE SEND THE COMPLETE UPDATED CODE FOR THAT MODULE I WANT YOU TO SEND THE complete and ENTIRECODE AND DOT SHORTCUT IT BY SAYING PUT THE REST OF THE CODE HERE. SEND THE ENTIRE UPDATED CODES HOWEVER IF A MODULE NEEDS NO UPDATE DONT SEND THEM AGAIN( FOR EXAMPLE BASED ON MY REQUEST ABOVE ONLY UTILITYMODULE NEEDS TO BE UPDATED AND THE OTHER MODULES CAN BE KEPT THE SAME, YOU SHOULD ONLY SEND ME THE COMPLETE UPDATED CODE FOR UTILITYMODULE) HOWEVER IF BASED ON MY REQUEST ABOVE IS ALL OF THE MODULES NEEDS TO BE UPDATED PLEASE FOLLOW INSTRUCTIONS BELOW BECAUSE ALL OF THE CODES ARE TOO LONG TO SEND IN ONE GO.

send me first the sheet1, thisworkbook, datavisualiyation, helper and setupmodule then after that ask me first if you can send the rest of the codes before sending the rest of the codes for the rest of the modules that will be needed. send the entire code for each of the modules.before giving me the updated codes check first for possible errors in the new updated codes fix that so that everzthing will work smoothly when I try them dont shortcut them. 


send only the complete updated of the modules that need to be updated DONT PUT THE REST OF THE CODE SEND THE ENTIRE UPDATED CODE FOR THAT MODULE
I TOLD YOU TO SEND THE THE ENTIRECODE AND DOT SHORTCUT IT BY SAYING PUT THE REST OF THE CODE HERE. SEND THE ENTIRE UPDATED CODES FOR THAT MODULE

I TOLD YOU TO SEND THE THE complete and ENTIRECODE AND DOT SHORTCUT IT BY SAYING PUT THE REST OF THE CODE HERE. SEND THE ENTIRE UPDATED CODES FOR THE MODULES THAT NEED TO BE UPDATED ONLY


THE CODES FOR THE ENTIRE TRACKER IS BELOW:
