Populating one variable based on another variable on a form

[Diana27]

Hi,

I have 2 variables in a variable set that I am using on a form.  The first variable is requested_for using the type Requested For:

I have another variable manager.

All I need to do is populate that variable (manager) with the manager of the user in Requested For.  This should be easy, however it is taking all day and I still cannot get it to work.  I'm about to go insane.

Thanks in advance for any assistance.

Diana

Thank you for your help but I couldn't get it to work.  I'm sure it is because I am new to this. I was able to use what tomaszsienkiewicz suggested.

Is Manager a refrence field to sys_user?

If yes, then you can use a reference qualifer and in that select advanced and mention

//check the variable name

javascript:gs.getUser().getUserByID(current.variables.requested_for).getManagerID();

And under attributes, add

ref_qual_elements=requested_for

asifnoor,

I have attached what I now have based on your reply.  It does not seem to work.

Here is how it looks on the form.

Ah okay.

Mention it like this.

javascript:'sys_id='+gs.getUser().getUserByID(current.variables.requested_for).getManagerID();
