Filtering MOSS 2007

[WERNERKUHN]

I want to create a Page1 with information about a customer. (name, address and phone number.)
On Page 2 (in the same site) i want to display the result from a SQL dB query but FILETERED on the customers phone numbere entered on Page1.
When changing the customers phonenumber, the result on Page 2 should reflect this dynamiccaly.

Thanks in advance.
