This won't work because you've got the expression in single quotes. In
order for the $cnt to be evaluated, you have to double-quote it.

This *should* work, except... what is $_POST['thisline']?

If this form is re-entrant (displays 4 lines, user hits "Done" and it
displays 5 lines, etc.), then you're going to have to save the $cnt
value in the $_POST array. Then you do something like:
<?php for ($i = 0; $i < $_POST['cnt']; $i++): ?>
<input type="text" size="5" name="thisline<?php echo $i; ?>"
value="<?php echo $_POST["thisline$i"; ?>"/>
<?php endfor; ?>
<?php $cnt = $_POST['cnt']++; ?>
<input type="text" size="5" name="thisline$cnt"/>
<input type="hidden" name="cnt" value="<?php echo $cnt; ?>"/>
Your question is a little unclear, so I may be misunderstanding what you
want.
