I am planning on using the below code for a login sequence and I want to know if it's secure enough. I'm new to programming and scripting (this is pretty much all premanufactured) and I want to make sure it's in good working order. Please help me correct any mistakes in my code with explinations, thanks.... oh yeah this is going to be run in conjunction with an asp page to make it harder to view the source... in case you wondered.

<HEAD>
