Hello DotNetNuke forums,

As an introduction, I am fairly new to web development, and while learning CSS and HTML has proved difficult, but managable, Javascript and Jquery has thrown me against a brick wall.

I have developed a DNN skin that at first glance, seems perfectly fine. I ran it through the WC3 Validator, and I receive no errors in my coding. I am using the DDR Menu (great menu!) on my page, and as far as I am aware, this drop down mega menu system is the only Javascript / Jquery running on my page. (Possibly another skin token?)

I have purchased a few modules to use on my website. I install the modules, and everything is working fine. I drop the module into a content pane on a page using my new skin. All of a sudden IE is detecting Javascript errors! I switched the page skin back to the default skin, and the errors are gone, so I KNOW it is something in my skin causing the Javascript conflicts.

The first module that is interacting with my skin, generating an error, is the OptIn Email module from DataSprings. I receive the two following errors from IE developer tools with this module active on a page.

SCRIPT438: Object doesn't support property or method 'extend' 
dnn.controls.js, line 4 character 57

SCRIPT5007: Unable to set value of the property 'tbDynamicH': object is null or undefined 
temp.yandasmpa.com, line 1060 character 32

The second module that seemed to be interacting negatively with my skin is the "Product Details" module from the Smith Cart E-commerce shopping cart. Yesterday it was generating an error related to jQuery "Hover Intent", and any area that called up a hover was non-functional, including the DNN control panel at the top of the page. However, today I can  not reproduce the error for some reason. It seems to be working now?

My question is this. I built my skin from the ground up, so the only Javascript or jQuery running on the page is that of DNN and it's skin tokens that I have dropped into the skin. 

There is obviously something I am doing incorrectly, some vital skin element I am leaving out, or an element that is required that I have neglected to put into the skin. As a new developer, I have done the research, and I can not pin down what it might be. Any help/pointer/links would be greatly appreciated. I am committed to successfully creating this skin, no matter how long it takes!

Thanks guys - 

Alex
