Multiple input fields search

[eluser]the_unforgiven[/eluser]
Hi all,

Help needed here:

I want to provide a form that has two input fields, date & time one field is called 'from' the other is called 'to' and also need to get the options from a dropdown menu that is pre-populated.

So if the user inputs a from and to date/time then selects a option from the dropdown I want it to search then database to match these and return the results, with pagination based on 15 results per page.

Code in my controller is here -> http://pastie.org/8505391

But it's not working and my form looks like this -> http://pastie.org/8505394

Really could do with some help on this please....
