Hi Dave,
Many thanks for helping with this.The price (0.00) has now been sorted thanks to your advice.
Sorry - I was being dense - the line is now correct:
<input <?php if (!(strcmp($row_WADAproducts['ProductLive'],1))) {echo "checked=\"checked\"";} ?> type="checkbox" name="ProductLive" id="ProductLive" value="1" />
Thanks for the assist!
