When it is a player's turn to make a purchase and it is possible for them to do so, the Share Purchase Popup Window is displayed. The player selects the shares to be purchased (by clicking on Available shares) and clicks the Ok button to make the purchase final. If a player wishes to unselect purchased shares, they click on the Purchased shares to return them.
The popup window automatically prevents the user from making an invalid purchase (trying to buy more shares than are available, not enough funds, or trying to buy more than the allotted maximum per turn).
Available - Shows a push button for each hotel chain that can be purchased (is formed and has shares available). If a chain's shares cannot be purchased due to insufficient cash, the push button for that chain is disabled.
Purchased - Box that shows the shares that the player has selected to be purchased. Each share purchased can be returned by clicking on it.
Cost - Display-only fields that show how much cash a purchase will cost (Purchase) and how much cash the player will have left after the purchase (Cash Left). Both values are adjusted according to shares purchased and/or returned.
Ok - Finalizes purchase.
