In SS1.0, I created a parameter and set its default value to number and when I try to get it using

nlapiGetContext().getSetting('SCRIPT', 'custscript_id')

it returns null. How could I fix this? Is there any other way to get from script deployment?

If the Deployment already existed at the time the Parameter was created or default value adjusted, I'm not sure if the default value would take hold on any existing Deployments. It's possible you'll need to re-create the Deployment; I'm not sure about that though. I suppose double-check the ID first

yes you are right. Deployment was already there. Thank you
