Here’s a quick and easy script to simply move a control on the panel, it takes the control name and new positions as the arguments.

Determining the name of a control is pretty simple, right click on the field -> Advanced -> Show Field Information

WIT0115 is the field name for the Item Label

And the script itself

/*
**	Name:	MoveControl.js
**
**	Description:
**	 Change the position of a control
**
**	Arguments:
**
**	<Control Name>,<column>,<row>
**
**	Eg.
**		WEITNO,15,2
**	 will move the control WEITNO to column 15, row 2
