There are a number of ways to manage kit prices.
Kit stock price
If Use Price is ticked, Jim2 will use this price unless any of the below apply.
If Use Price is unticked, Jim2 will use the price that is entered on the individual stock records.
Stock price level
If a price level is set on the kit (PL column), this will override the information at the top in the Kitting tab, even if it is ticked to Use Price.
If there is no price level set on the kit, Jim2 will capture what has been set in the Kitting tab of the Stock header.
Kit price level
Note that the price level on the job must be the same price level as set on the Kit.
If no price level is set on the kit, it will use what is set in the Kitting tab.
