I'm building custom page using Suitelet in Netsuite. I added select field and field options. How could I get selected text value from the select field.
I tried using request.getParamter('custpage_select_field') in the POST request, but it didn't work.
getParameter(), that seems to be the correct way to access field values in the POST. Without seeing additional code, there's not a lot of troubleshooting we can do for you. Can you update your question to add some sample code? - Mike Robbins
