Type Mismatch

I am an ASP developer seeking to build an interactive web site. Unfornately I'm so very frustrated and out of answers for a pivital part of my ASP programming. You see, A number of database Tables are linked together through a common ID Value in a Numbered Field.

These values are the ManagerID and the UserID. The ManagerID is used to get data about the manager and the UserID is used to get data about the users. Unfornately I am getting a ton of Type Mismatch results when I try and compare a numeric value to a string value stored in a Session Variable.

While using a Text Field methoud partially solves this problem, it causes a problem when records go above ID 9, as it instantly puts record ID 10 out of order in the table, thus causing severe problems with various functions in the project that add new records to the tables and generate a new ID value.

This is because when new records are added, it takes the last value stored in the bottom field and increments it by 1. thus since the last value would be 9, and if it increments to 10, you get a duplication error every time you try and add a record above 10. Thus only a Numeric Field which can auto-adjust according to the record values can this program function in the way it needs to.

For your review, here is the code of my Login Script page, I will site where the problem is. If I can find a solution to this problem, I can find a solution to plenty of others as well (As many other parts call on Numeric Field values to call records from the database.) Code:
