Making an NPC conversation loop till condition is met

[coffeepoppy]

I been trying to do this for like three days now and I can't get the damn thing to exchange all the investment tickets it has. It will exchange one, then go to get tickets. Which, it shouldn't. I desperately need help trying to get this thing to work

What the character has. 1k tickets
What I want it to do. Change the 1k tickets through an npc

###This will exchange tickets###

automacro exchange{
inventory "Thanks Invest Ticket" = 1000
call ticketexchange
}


macro ticketexchange{
do ai manual
do move 165 56 prt_gld
pause 1
do talk @npc (165 50)
pause 1
do talk resp 2
pause 1

if
(inventory "Thanks Invest Ticket" > 0){
call ticket exchange}

else (inventory "Thanks Invest Ticket" = 0){call storagestuff}

pause 1
do ai manual
timeout 20
release exchange
}}
