recieve field parameters from sharepoint form

[Rene Aime]

Hello!

in my contacts library (sharepoint) i like to create a button on my
sharepoint display form which
opens a new infopath form and pass some field values automaticly!

Example:
Button "Add new customer report form". Pass or copy the field customer
number (or object id) from the display form in the new infopath form.

Any ideas?

Thanks
René
