Parse error: syntax error, unexpected T_LNUMBER

I keep getting the following error:
Parse error: syntax error, unexpected T_LNUMBER

My code is as follows:
      $display_block ="
      <table width=/"100%/"  border=/"0/" cellspacing=/"5/" cellpadding=/"2/">
            <th bgcolor=/"#eeeeee/">#</th><th bgcolor=/"#eeeeee/">Date</th><th bgcolor=/"#eeeeee/">Description</th><th bgcolor=/"#eeeeee/">To/From</th><th bgcolor=/"#eeeeee/">Method</th><th bgcolor=/"#eeeeee/">Type</th><th bgcolor=/"#eeeeee/">Category</th><th bgcolor=/"#eeeeee/">Subcategory</th><th bgcolor=/"#eeeeee/">Amount</th><th bgcolor=/"#eeeeee/">Edit</th><th bgcolor=/"#eeeeee/">Delete</th>
      $option_block
</table>";
what am I doing wrong?
