Scheduled Script Parameter Problem

Hey guys,

I have a small issue.

I want to use a parameter from a user event to a schedule script:

User event code:
var params = [];
params['custscript2'] = stringA ;  // stringA contains something like 1212|321312|13213|
nlapiScheduleScript('customscript47','customdeploy1', params);

Schedule Script:

var massUpdateType = nlapiGetContext().getSetting('SCRIPT','custscript2');
nlapiLogExecution('DEBUG','Le champ de a est: ',massUpdateType);

the debugs gives me a null. The scheduled scripts does starts, but the parameter is empty.

Anyone sees my error?

Thanks.

The debug I'm getting
