I don’t know what you mean by “counting system”. What is it? Where is it? What’s it supposed to do? What is the problem with it?
I don’t see how adding a page could affect the functioning of another page.
Looking at the my-acc page, I see a number of issues:
The Repeater onItemReady() function sets the function that runs when a new repeated item is created. It should be in the page’s onReady() function, and not in a subroutine.
In the onItemReady() function, you are trying to set a text field #txtTemp that does not exist.
It seems to me that the problems you are encountering are not connected to adding a new page, rather they have more to do with the code in then my-acc page. You will need to fix the errors and the flow logic on this page.
