'nodes' does not name a type是怎么回事？

struct Node{
int w,x,y,z;
int close;
};
Node nodes[MAX]；

void getBana()
{
int w,x,y,z;
int m,n;
int head, tail;
memset(pa,-1,sizeof(pa));
head = tail = 0；

nodes[tail].w = a;
    nodes[tail].x = 0;
    nodes[tail].y = b;
    nodes[tail].z = 0;
    

想问一下为什么这里一直显示 'nodes' does not name a type，需要怎么改啊？

struct Node nodes[MAX];
