I have a problem with my code, and I can move or drag the name of the travel to my window "New Expenses", what I did here was to make a window where you can add multiple Expenses in one window, but in my code if I put <apex:inputfield value="{!Expenses__c.Travels__c}" required="true"/> drag me the name of the travel but when I get the expenditure does not keep in my travel.
As I can do to have the name of the travel there and save me the cost I do?

This is my code:

<apex:page StandardController="Expenses__c" extensions="AddExpenses" id="thePage" docType="html-5.0">

<apex:form >
<apex:sectionheader title="{!$ObjectType.Expenses__c.label} Edit" subtitle="{!IF(ISNULL(Expenses__c.Name), 'New Expenses',Expenses__c.Name)}"/>

<apex:pageblock id="pb1">
<apex:repeat value="{!lstInner}" var="e1" id="therepeat">
<apex:pageblock id="pb" title="New Expenses">
   
    <apex:pageBlockButtons >
      
        <apex:commandbutton value="Add" action="{!Add}" rerender="pb1"/>
        
        <apex:commandbutton value="Save" action="{!Save}"/>
     
        <apex:commandButton value="Reset" status="idStatus" onclick="this.form.reset();return false;"/>
        
        <apex:commandbutton value="Back to travel" action="{!Cancel}"/> 
        
               
        </apex:pageBlockButtons>
