未捕获的 ReferenceError：编译未在 HTMLInputElement.onclick 中定义

如何解决未捕获的 ReferenceError：编译未在 HTMLInputElement.onclick 中定义

我正在尝试制作一个供我个人使用的罐头消息生成器。我无法让第二个按钮工作。我在某个地方。这是我第一次尝试编码，所以请帮助..

     function write_response(){
      let verify_statement = document.getElementById('verifyStatment')
      let caseData = {   
        id: Date.now(),tasks: document.getElementById('task').value,slTag: document.getElementById('slTagId').value,orderId: document.getElementById('orderId').value,welcome: document.getElementById('welcome').value,closing: document.getElementById('closing').value,signature: document.getElementById('signature').value,sbtLevel: document.getElementById('sbtLevel').value,rma: document.getElementById('rmaId').value
      }   
    
      
      verify_statement.innerHTML = "Welcome Please Verify " + " Your task is " + (caseData.tasks) + " SL Tag: " + (caseData.slTag) + " Order #: " + (caseData.orderId) 
      + " RMA #: " + (caseData.rma);


    function para(){
      let compiled_all = document.getElementById('compileAll')
      let caseData = {   
        id: Date.now(),rmaId: document.getElementById('rmaId').value
      }

             
        compiled_all.innerHTML ==(caseData.welcome) + " We regret to inform you that during the provisioning of your recent order(s)# " + (caseData.orderId) + " we encountered a delay in provisioning. This delay is due to " +  (caseData.tasks) + " We will provide more information as it becomes available to us. Please let us know if you have any further questions or concerns and we would be happy to assist you."
        }

      



    };

第一个按钮生成段落没有问题，但是一旦我尝试第二个按钮，我就会收到主题错误。

   <div class="formBox">
        <input type="button" value="Verify" onclick="write_response() ;"/>
   
      </div>
    <div>
    <b>Always Double CHECK!</b>
    <p id="verifyStatment">  </p>
    </div>
    <div class="formBox">
      <input type="button" value="Generate" onclick="para() ;"/>
    </div> 

    <div>
      <b>You Lucky dog you ;)</b>
      <p id="compileAll">  </p>
      </div>
    </form>
</body>
