Common Fields tab

Use this tab of "Bulk Change" window to bulk edit fields that are non-textual in nature. The screen shot list all the available fields that can be bulk edited. Mutiple fields across different tabs can be used at once.
To bulk edit a field, check the box under the column "Change?" as shown below for the field "Fixed Price (for Fixed Price Listings):
The fields or selection boxes next the checked box get enabled. Enter/Select the value(s) for that field. In our case, we are incrementing the current price by 1.
Then in the next text box, enter the amount to add/subtract. Enter negative amount to subtract.
The description for each field is omitted here as these are the same fields that are displayed in various tabs of Full Editor.
