I have a Visualforce PDF quote that is taking informaiton from a field.  However it is not implementing the breaks or next line formatting.  I basically get a run on sentence which is confusing. (the field is !line.Description__c)  Here is the code that controlls this particular field.

<tr>
           <apex:repeat value="{!Opportunity.OpportunityLineItems}" var="line"> <tr>
            <td colspan="1"> <font face="Arial">{!line.Quantity}</font></td>
           <td colspan="2"> <font face="Arial">{!line.PricebookEntry.ProductCode}</font></td>
           <td colspan="6"> <font face="Arial" align="left" > {!line.Description__c} </font></td>
           </tr>
<tr>
          <td colspan="1" bgcolor="#fafafa"> </td>
          <td colspan="1" bgcolor="#fafafa"> </td>
          <td colspan="6" bgcolor="#fafafa"> </td>
          <td colspan="1" bgcolor="#fafafa"> </td>
          <td colspan="1" bgcolor="#fafafa"> </td>
</tr>
</apex:repeat> 
 

First time doing my own Visual Force Email Template.  I thought I had it all and then this message shows up:


Error occurred trying to load the template for preview: PDF generation failed. Check the page markup is valid.. Please try editing your markup to correct the problem.

Here is what my template looks like

<messaging:emailTemplate subject="Packaging Request from {!$User.FirstName} " recipientType="Contact" relatedToType="Opportunity">
<messaging:plainTextEmailBody >
{!recipient.name},
        
        We have a packaging request for {!$Organization.Name}.  Please find attached the PDF with all the relevant information
