// BUG FIX 04-03-2005 - There has been a problem in the Screen's section where you cannot add a new screen
// It was brought back to this file as the form was not called "mainForm". I have added
// an Is defined mainForm condition below to handle the situation... It is unknown if this 
// will have an effect elsewhere in the application. Alex Connell - 04-03-2005

// WAB March 2006
// Added handling of form.dirty.  If submit form is passed a second parameter promptForChange = 1 then the user is asked if they want to save the changes to the page
// function looks for hidden field dirty in the form
// defaults to promptForChange = 0 (which makes it backwards compatible)

function submitForm(wizardPage,promptForChange ) {
	promptForChange =  (promptForChange == undefined)? 0 : promptForChange ;
	
	// New 04-03-2005 - Check document.mainForm is defined
	if (typeof(document.mainForm) != 'undefined') {
	form = document.mainForm;
	// New 04-03-2005 - Check form.frmTask is defined
		if (typeof(form.frmTask) != 'undefined') {
			

			// promptForChange we ask the user if they want to save changes (only works if a dirty variable exists)
			if (promptForChange && typeof (form.dirty) != 'undefined') {
					if (form.dirty.value == 1)  {
						saveChanges =  confirm ('Save changes?')
						if (!saveChanges) {
							form.frmTask.value = 'doNothing'   // by doing this, won't do any of the updates
							form.frmWizardPage.value = wizardPage;
							form.submit()
							return
						}
					}
			}

		
			// if there is a function isFormOKtoSubmit defined then we run it
			if (typeof isFormOKtoSubmit != 'undefined')  { 
				OKtoSubmit = isFormOKtoSubmit()
			} else {
				OKtoSubmit = true
			}


			if (OKtoSubmit) {
				form.frmTask.value = 'save';

				// WAB 03/06/05   added check for wizard variable being past.  sometimes just want to stay on current page and don't pass in the variable
				if (wizardPage  )	{
					form.frmWizardPage.value = wizardPage;
