height is not a valid attribute of div element. You need to set the height in style attribute.

<div id="mtg-frame" style="border-style: none; border-color: inherit;
    border-width: 0; background-color: lightgrey;height:400;" class="auto-style1">
</div>

Some where you are using name attribute in your html. Make sure that the name attribute must have equal sign with value and value should be in quotation marks and the quotation marks must match.

Example

<input type="text" name="txtName" value="" />

Here the name attrubute has the value txtName and the quotation marks matches.
