upload custom package via module loader

Hi there,

Any body there could you please help ?

I'm following  Anastasiia Gubanovych's instruction here.

https://sugarclub.sugarcrm.com/dev-club/f/questions-answers/4795/api-filter-by-phone-number

I then generated a zip file 

office-phone-check.zip

via Logic Builder tool which basically just allow numbers:

And then I uploaded this zip file via 'module loader' and installed it.

But when I create a new Contacts, it doesn't work. Even I enter a string in the 'office phone' field, I can still store the value.

Could anyone please suggest?

Million thanks!
