// Function: isNumber
// Purpose: Checks to see if the control that currently lost focus has a valid numeric
// value.  If not set the control as the ERRORCTL and then set the error flag.
// We can't maintain focus on the error control here, so when the onfocus event
// of the next control fires we place focus back on ERRORCTL and inform the user
// of the problem. In this way we force the error to be corrected. 
// See setEditorValue function on the parent page that included this script.
// 
// Paramters:
//-----------
// ctlSrc: the control whose value is to be verified.
// errorMsg: the message to be displayed on error.
// 
// Notes on the variables ERRORCTL and error:
// ERRORCTL: a global variable (page scope) for tracking the last control to 
//           to contain an error.
// error:    a boolean flag indicating that an error has occurred.
