SugarCRM, being a web application, naturally prompts some users to ask whether it is possible to apply customizations to the system which in turn mimic behavior they may have seen on a random web site in the course of their general web browsing. A good example would be formatting numbers entered into the phone number fields in SugarCRM, similar to the manner in which many web sites handle that type of data on a contact form.
If you have not already done so, download the phone formatter module from SugarForge.org. We will not be installing the module, just examining some files. Thus, simply download the most current version of the module and do not concern yourself with the version of SugarCRM you are using.
