A Pronoun is a word or phrase used in place of a noun. A Pronoun must always agree with its antecedent (the noun or pronoun it refers back to) in Person, Number and Gender. This is called pronoun-antecedent agreement. In the above sentence, the person form of the pronoun and antecedent do not agree. Hence, the statement is false. The pronoun 'your' is in second person case but the antecedent it refers to 'a customer' is in third person case. One way to resolve this disagreement is to make the antecedent a second person noun 'you'. Therefore, the sentence will read: As soon as you click yes, your details are processed.
