Please help me to know where error:confused:

thanks advanced

if you don’t have a debugger, then another option to help debug your code is to place an alert() one at a time, or multiple if you prefer, at various points in your code to confirm

  1. your code is actually getting there

  2. check the values of varibales are correct at that point.

what mean <<then another option to help debug your code is to place an alert() one at a time, or multiple if you prefer, at various points in your code to confirm>>
