HI everyone.

If the button is not clickable.. TeamHeader.vue file.

@click="this.$emit('add')"> Add Member

If teams data or member data is not access in component.

Then this is fix, TeamHeader.vue. [Not the best Way]

`<script setup>
import {useTeamStore} from "@/stores/TeamStore";
// Import your Pinia store

// Use the Pinia store to access state
const teamStore = useTeamStore();
</script>`

//user
:disabled="teamStore.members.length === teamStore.spots"
