Answer 1

That is not the way you concatenate Strings in PHP. You aren't allowed to nesting <?php tags.
Instead of
echo '<input name="transactioncode" type="hidden" value="'<?php echo $transactioncode;?>' />';
Do the following:
echo '<input name="transactioncode" type="hidden" value="' . $transactioncode . ' />';
Simply add a . character between the parts you want to concatenate.
Edit:
And to finalize the answer, you should also be cautious about user inputs. They can be evil! In this case you should remove HTML characters via htmlspecialchars():
echo '<input name="transactioncode" type="hidden" value="' . htmlspecialchars($transactioncode) . ' />';

Answer 2

Take a careful look at line 28:
echo '<input name="distination" type="hidden" value='<?php echo $distination;?>' />';
The problem is fairly obvious. Pay attention to quoting.
As a general rule: If an error report gives you a line number then take a good look a that line. Sometimes you can break the line in half and re-run the test to see if it still occurs on the same line or the next one to tell which half of the line the issue is in. For example break your line above like this to test it:
echo '<input name="distination" type="hidden"
value='<?php echo $distination;?>' />';

Answer 3

What you are looking for is called "concatenation".
You can "concatenate" (listen append) 2 strings using a dot :
echo "string1"."string2";
will display "string1string2"
You can also concatenate a string and a variable :
$string2 = "string2";
echo "string1".$string2;
So in your example, it will be :
echo '<input name="transactioncode" type="hidden" value="'.$transactioncode.'" />';
echo '<input name="cusid" type="hidden" value="'.$cusid.'" />';
echo '<input name="total" type="hidden" value="'.$total.'" />';
echo '<input name="grandtotal" type="hidden" value="'.$grandtotal.'" />';
echo '<input name="totalcharge" type="hidden" value="'.$totalcharge.'" />';
echo '<input name="portal" type="hidden" value="'.$portal.'" />';
echo '<input name="distination" type="hidden" value="'.$distination.'" />';
