Manipulating data from user input to form

Manipulating data from user input to form

Hey Guys,

I am collecting mobile numbers on a form which are inputed in the standard format. When the user hits submit I want to add a "44" to the beginning of the number and a "," followed by a space at the end. This would then be placed in the data column.

I am not very good at writing these solutions and would be great if someone could help me out, step by step.

Many Thanks

Simon.
