 Yes above it is that I have done so far  
    
 The file exists, I have done a double check.  
 This is my html table  
  & lt; Table id = "internalActivities" & gt; & Lt; Thead & gt; & Lt; Tr & gt; & Lt; Th colspan = "3" & gt; Internal activities & lt; / Th & gt; & Lt; / Tr & gt; & Lt; / Thead & gt; & Lt; Tbody & gt; & Lt; TR & gt; & Lt; Td style = "text-align: left;" & Gt; & Lt; A href = "display-call.php? Account_id = 9 & amp; amp; amp; amp; call_id = 1128" & gt; & Lt; Strong & gt; Initial development & lt; / Strong> & Lt; / A & gt; & Lt; / TD & gt; & Lt; Td style = "text-align: center;" & Gt; 05/23/2013 06:19 AM & lt; / Td> & Lt; Td style = "text-align: center;" & Gt; Name & lt; / Td> & Lt; / TR & gt; & Lt; TR & gt; & Lt; Td colspan = "3" & gt; & Lt; Em> Call results: Messages delivered - follow up to 21 days later & lt; / Em> & Lt; Br / & gt; & Lt; P class = "sub_note" & gt; At the bottom of the list & lt; / P & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt; TR & gt; & Lt; Td style = "text-align: left;" & Gt; & Lt; A href = "display-call.php?

 I have not found any errors but do not display the table as it should. Merge two columns to U because of using collspan in 
 
 some  td    
 Should not. See my HTML coding if it works, then do its job.    & lt; Div & gt; & Lt; Table ID = "Internal Activity" cellpadding = "0" cellspacing = "0" range = "1" square = "display" width = "100%" & gt; & Lt; Thead & gt; & Lt; TR & gt; & Lt; Th & gt; Internal activities & lt; / Th & gt; & Lt; Th & gt; & Lt; / Th & gt; & Lt; Th & gt; & Lt; / Th & gt; & Lt; / TR & gt; & Lt; / Thead & gt; & Lt; Tbody & gt; & Lt; TR & gt; & Lt; Td style = "text-line: left;" & Gt; & Lt; A href = "display-call.php? Account_ id = 9 & amp; amp; call_id = 1128" & gt; & Lt; Strong & gt; Initial development & lt; / Strong> & Lt; / A & gt; & Lt; / TD & gt; & Lt; Td style = "text-align: center;" & Gt; 05/23/2013 06:19 AM & lt; / Td> & Lt; Td style = "text-align: center;" & Gt; Name & lt; / Td> & Lt; / TR & gt; & Lt; TR & gt; & Lt; TD & gt; & Lt; Em> Call results: Messages delivered - follow up to 21 days later & lt; / Em> & Lt; Br / & gt; & Lt; P class = "sub_note" & gt; At the bottom of the list & lt; / P & gt; & Lt; / TD & gt; & Lt; TD & gt; & Lt; / TD & gt; & Lt; TD & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt; TR & gt; & Lt; Td style = "text-line: left;" & Gt; & Lt; A href = "display-call.php?
