Hey!

I would like to move the OK & Cancel Buttons on the Contact Form and I placed this code:
<div class="toolbar" id="toolbar" style="float: right;">
<button class="hikabtn hikabtn-success" type="submit"><i class="fa fa-check"></i> <?php echo JText::_('OK'); ?></button>
<?php if(hikaInput::get()->getCmd('tmpl', '') != 'component') { ?>
<button class="hikabtn hikabtn-danger" type="button" onclick="history.back(); return false;"><i class="fa fa-times"></i> <?php echo JText::_('HIKA_CANCEL'); ?></button>
<?php } ?>
</div>

at the Bottom of the Product / Contact - View file.
It works and moved the Buttons to the bottom but the form posting stops functioning.
Could you please point me in the correct direction?
