OK so I did a little reading on this thread (sorry I was searching easypopulate instead of easy populate so I missed the previous explanations of this problem) but I am still concerned.

I read that EZP does not show the success report screen if there are over X number of products. But it DOES still work I have read. Here are my questions now:

Approximately what is X?

Does X stand for number of products CURRENTLY on site or number contained inside the uploaded spreadsheet? Because I never had this problem during initial population. Its only been happening now that I am trying to update/add more products.

EZP will not return a success screen even when uploading using the "Split File" function?

When importing the split files one at a time will I still not get a success screen even tho the files only have 100 products each?

This is all going to be automated so the success screen is not required but I need to make SURE it works 100% of the time anyway. From what I read it will. Is this correct? TIA!!
