controling variable in script Options

[Mazel]

Ummm... hello,,
Do anyone have any idea of how to put variable in script.
I wanna make a discount shop, my simple plan is adding the variable that controlled outside the script but will affect the script.
New Price = A (item price) / B (variable value) * 100
but I can't do that. *looks like it's not as simple as I thought *
the game always went error, help me please....
using $game_variables[B] completely the only thing I can do, but it's not the answer

No script + no error message = no help.

How can you possibly expect for someone to correct something they can't even see?

I can re-write the entire thing so it's correct

That, and I'm guessing that variable B was set to 0...

Thank you so much Night Runner .\(^o^)/
I really appreciate it, since I got really stressed to figure it out,

my script is totally awful, the last thing I wrote is :

CODE

# Buy process
        $game_party.lose_gold(@number_window.number *( @item.price*$game_variables[4]/100)

I just wanna the price changed when it's a buy command, I don't wanna losing any gold for selling.

so after many trial and error, I decide to give up on script and using event instead.

CODE

control variable: [0001:Gold] = Gold
control variable: [0005:disc] = 100
control variable: [0005:disc]/= Random No. (2...5)
Text: Today discount is \v[5]%!
    : Enjoy your shopping

Control Variable: [0002:Gold2]=Gold
Control Variable: [0003:Gold return]=variable[0001:Gold]
Control Variable: [0003:Gold return]-=variable[0002:Gold2]
Text: You've shop for \v[3] Gold
    : Here's your change, Sir
Control variable: [0003:Gold return]*=variable[0005:disc]
Control Variable: [0003:Gold return]/100
Change Gold: + Variable [0005:Gold return]
Text: Receive \v[3]Gold

But I forget one thing... it also have the access to sell menu! it decrease the value of gained gold, huwaahhh.... that's why I asked to this forum, looking for some working script. I'm really glad Night Runner answer it. And thanks for allowing me to copy paste it ^^. Yesh!

Hiks, why do scripting isn't as easy as it look like >______<,,,
