Once you've fixed that critical security vulnerability in your code, you'll need to check that the values you're trying to insert match the data types of the columns in your table.

You should also avoid using CInt and CDate to convert user input. If the user types in something that can't be converted, you'll get an exception. Instead, use Integer.TryParse[^] / Date.TryParse[^] and display a warning to the user if their input is invalid.
