Custom Script help: requiring Material Request reference for specific condition

[lxnow]

My intension to require a user to have a Material Request referenced in each stock entry line item (in Stock
Entry Details table) based on the following conditions:

1. purpose is material receipt
2. receiving location is Warehouse X (a specific warehouse)

In other words, for the specific Warehouse X, the user must create the Stock Entry from a Material Request if it is receiving via purpose material receipt. 

The script logic is to compare the # of line items vs the number of line items with a Material Request referenced. If # of lines > than lines with Material Request, the form should not save.

This is the more complete script: http://pastebin.com/Z3YJ52Se

Unfortunately, I think there is something wrong with the script as it makes saving the form not possible.

I have added an example in github wiki. Please check https://github.com/frappe/frappe/wiki/Client-side-scripting#wiki-material-receipt-in-warehousex-must-be-made-against-material-request

Thanks Nabin. Example works, but I had to add a closing parenthesis; have edited the wiki. And at least for hosted accounts, frappe.model.get doesn't work yet, so using wn.model.get instead.
