problem with macro command NPC.Buy

[Bbotone]

When I run the macros on cavebot, it doesnt buy potions on one npc, nor buy rope and shovel in other npc, but it works fine when I debug the script near the npcs.
I added a "Self.Say(!qtmp! !qthp!)" to debug, it says "8 8" on default, which is the quantity of potions that Npc.Buy uses as value.
It's weird because it says "hi"/"trade" to npc, and "8 8" on default, and when I debug the macros near the npcs, it buys the potions correctly

anyone can help?
thanks in advance

WHy use all this ? and all these variables? all you have to do is , Npc say hi / trade , then click Add -> trade -> Buy, just say how much potions in total to buy and there you go done -.- wtf is the point of all this crap you did?

same with rope . just Add -> trade -> Buy , Id rope and how much ropes to buy ...

If i helped a rep+ would be nice , thanks.

I agree, I reduced the macro "buyropeshovel"
but I still want to know why didn't work

[erykans]

Hehe thanks for agreeing with me,
Variables is a new feature in Bbot , im not good with them yet but im getting there, Wait untill somebody who is good with variables answer and then you will know ..
