There are two ways to edit item reserves using BidJS. Note that reserves can only be added to timed items in the Marketplace or in an event auction - they cannot be added to webcast items.
Edit a Reserve in the Bid Table
Here are the steps:
Login to admin and go to your auction
Click the Bid Table button in the top right corner to open it
Find the item you wish to edit the reserve for
In the Reserve column, edit the value
Hit the 'conf' button to confirm the change
Confirm again using the green button in the pop-up window
See that your Reserve is now updated
Edit Reserve in Bulk Edit
A second method to edit your reserves is using bulk edit. Click here for instructions on editing your items.
