Getting a value from a Snapshot query into a field in a form

[ForcedToUseIt]

How can i get a value from a snapshot query and put that value into a field in another table?

The snapshot query is like this (qrySnapshot):

DocID
NewReference

And the table has fields like this (tblDocs):

DocID
Reference.
...

I want to press a button and through VBA put the (text) value in NewReference into the field in Reference where qrySnapshot.DocID = tblDocs.DocID.
I have a field on the form that shows this tblDocs.DocID and i want to use that value to compare with the qrySnapshot.DocID value.

To accomplish this I think I have to run the query form vba and get the value through it somehow. Any ideas are welcomed

P.s. Im using DAO

Thanks alot
