If you use code tags, I will take a look at your code.

Please use the [code] and [/code] tag pair to enclose your code. This way the proper indentations will show, making your code readable.

[Namibnat]

Put your code in code tags, and try to boil it down to what is going wrong a little.

Your 'View' and 'view' should be the same caps.
