Possible Problem With Long Product Numbers

[mj999 0]

I'm using the latesy EasyPopulate with support for attributes and added the code for product_retail_price. All that seems to be fine but here's my problem. Things are going haywire with the process and it appears to be related to products with longer numbers or, possibly, image names. In this store they are the same for all names and images with ".jpg" on the end of each image. Products with less than for digits in the product number seem to be fine but longer numbers aren't. That's my guess, anyway. Anyone else have any experience with this?
