To Modify one or more items in one or more line product items in the HeffComm shopping cart product file, click on the "Modify" button as shown below:

The following screen should appear on your screen:

This is your complete product file displayed in a table on your screen. On the right side of the screen is a scroll bar (not shown) which you can use to scroll up or down the list. It also works using a "wheel mouse". Scroll to the line item you want to modify, then click in the field you want to modify and edit your data.

When you have completed updating all the field on all the products you want to update, on the bottom left side of the page shows an update button (see below) which will replace the real product file with the current temporary file that you just edited.

That is all there is too it!

If you programmed your web pages to get the price from the product file, the price on the page changes for the next user to load the page after you have updated the file.
