Create Regular Expression 1

[hmckillop]

I am trying to create a regular expression to accept a currency amount including decimal point (but not required), allowed up to 15 digits to the left of decimal and up to 4 digits to right. Amount must be greater than 0.
I just cant seem to create this, any help appreciated.
Thanks
