Some of the menu links are mouse-overs and some are not?
This is from the Services page:
<div class="Object1420"><a href="index.html" ><img src="files/IMG_21.jpg" alt="" width="139px" height="35px"></a></div>
<div class="Object1421"><img src="files/IMG_22.jpg" alt="" width="197px" height="91px"></div>
<div class="Object1422"><a href="Services.html" onMouseOver='img_mo0.src="files/mo_IMG_23.jpg"' onMouseOut='img_mo0.src="files/IMG_23.jpg"'><img src="files/IMG_23.jpg" name="img_mo0" alt="" width="139px" height="35px"></a></div>
<div class="Object1423"><a href="Services.html" onMouseOver='img_mo1.src="files/mo_IMG_24.jpg"' onMouseOut='img_mo1.src="files/IMG_24.jpg"'><img src="files/IMG_24.jpg" name="img_mo1" alt="" width="139px" height="35px"></a></div>
<div class="Object1424"><a href="Crowdfunding.html" ><img src="files/IMG_4.jpg" alt="" width="577px" height="37px"></a></div>
<div class="Object1425"><a href="index.html" ><img src="files/IMG_5.jpg" alt="" width="248px" height="55px"></a></div>
There's 2 links to services with mouse-overs (one goes to contact), one link to crowdfunding (which doesn't work for me/Firefox), and 2 links for index.
Maybe you could get them all working properly on one page, then copy/paste the menu onto the other pages.
