I have created a page that displays opportunities across related accounts and I would like to allow users to create a new opportunity associated to one of those accounts directly from the page. Because I have a search function on the page as well, my form has multiple functions based on the action button used. If I simply added input fields for an Opportunity object, the field requirements (name, close date, etc.) would cause errors when searching. To resolve this I have created a custom Opportunity-like object (tOpp__c) without required fields and then I build a new Opportunity object in Apex. The problem I am running into is passing the selected option from a selectList into the controller so that I can populate fields on the Opportunity that require a lookup (Account, Owner, etc.) single-value input fields are passing data fine and the HTML output of the page appears to show the selected list populated correctly, but I get a null value in my debug logs for the selectList variable.

            List<Account> accts = [select Id from Account where Name = :(tOpp.Account__c) limit 1];
            if (!accts.isEmpty()) {
