Eu não estou conseguindo fazer com que meu modP seja reconhecido. Isso é um formulário de busca

Alguém pode me ajudar?

public Busca() {
    initComponents();

Usando netbeans, certo?
Onde está a declaração do modP?
Provavelmente em lugar nenhum (ou em um canto escondido do código, que nem o compilador java encontra).

Ele está em uma classe global. E sim, estou usando o NetBeans.

Ele está em uma classe global. E sim, estou usando o NetBeans.
Classe global? Toda classe java em que a palavra reservada public consta é global.
Se você quis dizer que a variável modP é uma constante, sugiro que referencie o nome da classe.
Senão, preciso que você explique o que quis dizer com classe global.
Exemplo:
public class ClasseGlobal{ public static final String CONSTANTE = "Teste"; }
E a chamada:
public class OutraClasse{ public void exibeMensagem(){ System.out.println("Isto é um " + ClasseGlobal.CONSTANTE; //Saída esperada: Isto é um Teste } }
