blaze doesn't know what he's doing :D
also, i'd probably check if they're trying to jet, so you can display the price and item name
0 onactivate>self>vce_ifvalue[<var:pl:jetting>][==][1][1 2]
1 onvariablefalse>client>chatmessage[<color:ffffff>Jet and click to buy (item name) for (point value) points.]
2 onvariabletrue>self>vce_ifvalue[<var:cl:score>][>=][(amount)][3 7]
3 onvariabletrue>player>additem[(item)]
4 onvaraibletrue>client>incscore[-(point value)]
5 onvariablefalse>client>vce_modvariable[points][set][(ammount for item)]
6 onvariablefalse>client>vce_modvariable[points][subtract][<var:cl:score>]
7 onvariablefalse>client>centerprint[<color:ffffff>You need <var:cl:points> more points to buy this.]
note, you may want to delay line 5 by a little, and 6 by a little more (33 and 66 should work fine)
