Validation errors

My site ( www.the-authors-club.com ) displays as it should in Internet Explorer, but not in Chrome or FireFox. I validated the site using the W3C validator and it came back with 5 errors:

Line 256, Column 778: Duplicate ID filter_6_1.99.…_of_Book" type="text" id="filter_text_Name of Book" value=""/></div>

Line 256, Column 530: The first occurrence of ID filter_6_1.99 was here.…_of_Book" type="text" id="filter_text_Name of Book" value=""/></div>

Line 258, Column 196: Bad value filter_text_Name of Book for attribute id on element input: An ID must not contain whitespace. </form>
Syntax of id:An ID consists of at least one character but must not contain any whitespace.
Line 345, Column 5: No p element in scope but a p end tag seen. <h3>Latest products</h3>


Line 408, Column 5: No p element in scope but a p end tag seen.


Could these errors be the cause of my site not displaying (i.e., buttons not working, links don't work, form fields not working) correctly in Firefox and Chrome?

Hi there,

Those are html errors, I'll try to fix it but it's not the source of your issue.
You actually have a huge div which overlaps you first product, that's why you can't click the buttons.
Here is a screenshot to make it clear:




It's due to your template, try to add some css to fix it!

I figured out that it was my logo causing the problems. Thanks, though.
