请帮我看下扔雷换刀的这段代码，有个问题！

ttboy

最近扔雷炸服麻烦死，因此得到扔雷换刀的插件，但是，听冰河说，C4也能炸服， 真是没办法，于是自己动手，依葫芦画瓢，改了了一下，把前换扔雷的代码加到了后面，但可能不知道CS武器代码，扔C4换刀无效请帮我看看哪里错了。
我改了三个地方。请教，哪里错了。
new const sModel_c4_w[] = "models/w_c4.mdl"

register_event("CurWeapon", "event_CurWeapon_CheckWeapon", "be", "1>0", "2!4", "2!9", "2!29", "2!25", "2!6")

|| ( !equal(sModel, sModel_HeGrenade_w) && !equal(sModel, sModel_SmokeGrenade_w) && !equal(sModel, sModel_FlashBang_w) && !equal(sModel, sModel_c4_w)) )
