form fields... trying to return all values in a query

G

I currently have a form and the path is [Forms]![SVP]![SVP]. I have
created a form with a drop down list that queries my main sheet for
all the possible fields. I cant seem to figure out how to write an
expression that allows me to leave it blank and then return all fields
OR choose a value and return only the matching values.

I hope this makes sense.
