crmForm to Xrm

I am learning to code. Please excuse any mistakes I made in terminology.

I changed the code from crmForm to Xrm and it worked with one form but not with another. They are identical but I cannot seem to find the problem. Here is the beginning of my code, possibly where the error is.

old code:

/* Enable/Disable form fields based on Payment Type */

function set_paymenttype() {

switch (crmForm.all.new_paymenttype_optionset.DataValue)

new code:

/* Enable/Disable form fields based on Payment Type */

function set_paymenttype() {

switch (Xrm.Page.getAttribute("new_paymenttype_optionset").getValue()){

I get the following error message on opening the form.

The was an error with this field's customized event

Field:window

Event:onload

Error:'set_paymenttype' is undefined

Followed by:

The was an error with this field's customized event

Field:crmForm

Event:onsave

Error:'Form_onsave' is undefined.

Here is the updated code for 'Form_onsave'

function Form_onsave() {

Xrm.Page.getAttribute("new_totalleasepayment").setSubmitMode("always");

Xrm.Page.getAttribute("new_estsaleprofit.setSubmitMode("always");

Xrm.Page.getAttribute("new_estsaleprofitmargin.setSubmitMode("always"); }

Here are the Event Handlers properties for both events.

Let me know if you need any more information. The rest of the code is not every long. I can upload it if necessary.

Thank you for any assistance in this matter.
