Could someone point out to me why the patientMatch function doesn't appear to run. I need to match the exam info with the patients information to display on a table. Running the function outside of the displayExams functions has no issues, but once its inside the displayExams function it doesnt run. Also logging out patientMatch inside the displayExams function comes back with undefined.

```
function examPatientMatch(exam) {
    for (let i = 0; i < patients.length; i++) {
        if ( exam === patients[i].PATIENT_ID  ) {
            return patiens[i]
        } else {
            console.log('not it')
        }   
    }
}

function displayExams(exams) {
    let examHTML = '';

    exams.forEach((exam, index) => {

        let patientId = exam.patient_Id;
        // let imgStudyDays = exam.Diag_to_img_study_days;
        // let imgStudyHrs = exam.Diagnosis_to_imaging_time_hrs;
        // let imgDesc = exam.Image_study_description;
        let studyMod = exam.study_modality;
        let keyFind = exam.key_findings;
        let img = exam.png_filename;
        let examId = exam.exam_Id;

        examPatientMatch(exam)

        examHTML += `
        <div class="exam-row" data-index="${index}">
        <div class="cell" data-title="Patient ID"><a>${patientId}</a></div>
        <div class="cell" data-title="Exam ID">${examId}</div>
        <div class="cell" data-title="Xray"><img src="https://ohif-hack-diversity-covid.s3.amazonaws.com/covid-png/${img}" alt="Xray"></div>
        <div class="cell" data-title="Key FIndings">${keyFind}</div>
        <div class="cell" data-title="Study Modality">${studyMod}</div>
        <div class="cell" data-title="Age">51</div>
        <div class="cell" data-title="Gender">Male</div>
        <div class="cell" data-title="BMI">37.7</div>
        <div class="cell" data-title="Zip Code">722</div>
        </div>`
    });
    examTable.innerHTML += examHTML;
}
