Problem

I've got input field and I want to check dot existence for value of price input field. The value will be look like this `12.00`. Here is my code ``` <g:textField class="span3" id="price" name="price" required="" pattern="\d+(\.\d{2})?"/> ``` I write something like this `\d+(\.\d{2})?`, but received error. Any suggestions ?
