Floating Side Module Overlapping Bottom Position

I have Floating Module CK installed on my site and enabled on one of my modules that I have assigned to a sidebar position in my site's template. This is working great except for one problem. When I scroll to the bottom of a page, the module is overlapping another module that I have assigned to my template's footer position. I tried putting the id of the footer div, #tm-block-footer, in the "Bottom limit" field, but that is not working.

Here are all the settings for my module.
Enable the floating module: Yes
Type of floating: On scrolling
Vertical offset: 100
Vertical margin: 200
Background color: #92aca6
Floating CSS class: blank
Bottom limit: #tm-block-footer
Bottom offset: 0

How can I fix this problem?

Hi CEd,

Is there a way I can send you the URL of the page without posting it on this public forum? It is our company's policy not to post any of our sites' URLs on public forums.

Thanks!

yes, use the contact link at the top of the page

Ok perfect. Just sent you the link via the contact form.

I have just tested , try to add this CSS in your template
