How to check both Read only and Mandatory in Variable in Record Producer?
What scripts should I put in Default Value?

Any help would be appreciated.

@Daemon5 

Should it be when form loads or based on some variable change?

When form loads -> onLoad catalog client script

When variable changes -> onChange catalog client script on that variable

Nothing to do with Default value. Default value is used to auto-populate variable when form loads

Thank you so much for the information!

I would like to set Read Only and Mandatory when Form load in Catalog client script.

I have tried the following script, but it only executes ReadOnly.

function onLoad() {
	g_form.setReadOnly('fieldsname', true) && g_form.setMandatory('fieldsname', true); 
}

Any script improvements would be helpful!
