Sidney's vendor with proceeds share

Thank you for taking an interest in my "Vendor with proceeds-share"

As ever I can never find something that does exactly what I wanted so I ended up making one myself.
This vendor overcome a problem I faced when I wanted to be able to share the proceeds from shop sales with a business partner.
Usually when you buy something the money goes direct to the owner and you have to have a manual process of sharing the proceeds later.
In this case I wanted a easy way to be able to share the profits between myself and my business partner.
Also to be able to keep track of who purchased what and when.

I have found this vendor very useful and I thought you might too!
Please note that the vendor does not require a sharer. If you have not allowed one then the owner keeps all sale proceeds.

Now for the instructions and details of what it does.

The vendor has three modes:
"contents unavailable"
This is the default (reset) mode and also when the vendor has not been configured correctly.

"edit mode"
This allows the owner and sharer, if they exist, to configure the vendor.

"ready-to-sell mode"
When touched the vendor gives a copy of the notecard and the texture. A message is sent to the owner and sharer telling them that "Joe Bloggs" has taken information about the item on sale.
When paid the vendor gives a copy of the item on sale. The price paid by the purchaser is divided between the owner and the sharer if one exists. A message is sent to the owner and sharer telling them that "Joe Bloggs" has taken purchased the item on sale.

Things only the owner can do.

"reset"
This allows the owner to reset the script and bring it back to default settings.
There is a "yes_reset" button to make sure this is not done by accident.

"set_share%"
This allows the owner to choose the percentage of the sale that they keep! This is done using chat on one of the edit channels (e.g. "/111 80" would give 80% of sale proceeds to owner and 20% to sharer). This defaults to 50%.

"share"
This puts the vendor in a mode where the next person to touch it becomes the sharer.
The sharer is able to control and edit the vendor but not the commands in this section.

"no_share"
This revokes the sharer. They will get a message to tell them that this has happened.
There is a "yes_revoke" button to make sure this is not done by accident.

Things both owner and sharer can do.

"empty"
This allows the owner/sharer to empty the vendor and resets the price, you will need to do this if you want to change the contents or if too many objects/textures/notecards have been added.
There is a "yes_empty" button to make sure this is not done by accident.

"set_price"
This allows ther owner/sharer to set the price. This is done using chat on one of the edit channels (e.g. "/111 20" would set the price to L$20).

"edit_channel
This allows the owner/sharer to change the chat channel used to set the selling price and percentage owner keeps. There are four options: "ch_111", "ch_222", "ch_333" and "ch_444".
Hopefully one of these will not clash with nearby objects.

"edit"
This puts the vendor into edit mode. A display above the vendor shows the state of what has been configured.

"done"
This cancels the edit mode. It results in one of two things happening. If the sanity check for object, notecard, texture and price passes then the vendor goes into ready-to-sell mode. Otherwise you are told what is wrong and the vendor goes into unavailable mode.

The vendor is modify so you can change the shape from a box to a wall hanging.
Please let me know if you have any questions or problems. I am happy discuss alterations or new commissions as required.

Happy selling and sharing your proceeds.
