How to populate RITM variables value in Catalog task variables

[RudhraKAM]

Hello there , 

We have a catalog item with 2 Variables Variable1 will be displayed on the form and Variable 2 is hidden but available on catalog task  when the request is raised the variable1 value  entered by the user should be populate in the  variable 2 on catalog task , 

I tried Below scenarios : used the On submit client script (its populating the values on catalog task but when ever i save the task all the values are clearing /deleting ) 

is there a way i can copy values form Variable A to Variable B on catalog Task ?

I also tried on catalog task advance script 

task.variable1= current.variable2 

and 

task.current.variable1= current.variable2

tried that but no luck

The variables on task is on variable editor , not sure how to point that ,, when i tried to point the variable to description , it is setting the value but as the variables are on the variable editor may be its not setting

When you put code like this in a background script, are you getting any output?

var reqItem = new GlideRecord('sc_req_item');
reqItem.get('64c14e82db058810744f4b8b0b9619ca');
reqItem.query();
if(reqItem.next()) {
  gs.info(reqItem.variables.variable_1);
}

its giving the value i entered

Now, if you're trying to get that value into a field on you task record, you should be able to assign it in the script field of your Catalog Task workflow activity. Try first assigning the value to the short_description on your task:

task.short_description = current.variables.variable_1.getDisplayValue();
