Gas Loop "For" and Call Function

I am trying to optimise something. My script:

function d1() {     
  for (i = 0; i < 1; i++) {    
     d1();     
   }     
   Logger.log("DONE!");   
 }

 function d2() {    
   for (i = 1; i < 2; i++)       
     Logger.log("IN PROGRESS...");     
 }

This script will never complete! But if I change to

function d1() {
  for (i = 0; i < 1; i++) {
    for (i = 1; i < 2; i++)
      Logger.log("IN PROGRESS...");
  }
  Logger.log("DONE!");
}

Everything perfect! What's my problem?

Oh, I'm stupid. of course I call d2().

My script is completely different, I tried to simplify, but I guess I'd better send the original, I hope it will be clear.

while writing the message and testing, I found my mistake.

loop for in projects.gs contain variable i loop for in holadays.gs contain varialble i too

I changed the variable and it's all right!
