Modified Shop Scene

I need a Modified Shop Scene to do the follwoing:

When buying a weapon or armor the message must appear to say: "dou you want to equip X"
where X is weapon or armor's name.
then the player choose YES or NO.
if he chooses YES then it must show a list of party member's name to choose ,then if a chosen actor can what is bought
then the weapon or armor will equip for chosen actor ,then a message will say"X equiped Y successfully"
X :actor's name
Y: weapon or armor's name
but if a chosen actoe cannopt equip a bought weapon or armor ,then a message will say "X cannot equip Y"
X :actor's name
Y: weapon or armor's name

Please mention to lines where there is texts to modify them if I want.
