After exporting an apex class from Sandbox to Production and removing all validation rule errors, I came up with the error in Spanish "La cobertura de prueba media de todas las clases y desencadenadores de Apex es de 74%, se requiere una cobertura de prueba mínima de 75%.".  How to over come this?

I'm trying to create a validation rule for our phone numbers. Every number has 3 parts:

Country Code (numerical, 2 digit starts with '+') --> +49
Area Code (numerical, min. 2 digit, max 5 digits, cannot start with 0) --> 42; 421; 4218; 42189
Number (numerical, no digit limit, cannot start with 0)

Examples:

+49 123 1234567

Thanks for help.

 Everytime I try to save a visualforce page in the setup section I get the following error:Error: <apex:page> is required and must be the outermost tag in the markup at line 1 column 1

I get the error if i edit the page, if i try to rename the file or even if i open it up and just hit save. This is happening on all visualforce pages. Any ideas? My Code: (This is just the standard SFDC Login Visualforce page.
