How to delete value from table when having multiple conditions?

it should still fix some issue The short answer is likely that you need a space before AND in your string. It looks like you assume numbers will be entered in each of the textboxes, but you don't enforce that, so different errors may occur depending on the content of those textboxes.
The longer answer is DON'T DO IT THIS WAY! You're opening up your code to SQL Injection attacks. Use parameterized queries instead as shown in this reference.

To fix the issue you can do I have a subquery that returns a subset of values from a table like: , Wrap your sql into a cte and then delete FROM your_cte.
 --insert sub query here...

This might help you ID is your PRIMARY KEY in the table, so you can get MAX(id) to be your Reservation ID,then use NOT IN to delete by ID without MAX(id)
You can try this.
DELETE ba FROM bid_account ba
  SELECT max_id FROM 
      SELECT auction_id, bidding_price, MAX(id) max_id
      FROM bid_account 
      WHERE bid_flag = 'd' AND bidding_type = 's'
      GROUP BY auction_id, bidding_price
    ) t
DELETE ba FROM bid_account ba
  SELECT min_id FROM 
      SELECT auction_id, bidding_price, MIN(id) min_id
      FROM bid_account 
      WHERE bid_flag = 'd' AND bidding_type = 's'
      GROUP BY auction_id, bidding_price
    ) t
