Modules & VBA :: Recreate Old-style Parameter Query Mail Merge

I am trying to create VBA code (I have very little experience of VBA) to recreate a parameter query mail merge, which Access 2013 cannot achieve with the controls provided.I think that I need to assign a variable to the value of a control on my form then assign that variable to the relevant criteria section of my query.

Code:
DIM RefNo as String
DIM IDNo as String
RefNo = Me.[Reference Number].Value
IDNo = Me.Text582.Value
DoCmd.OpenQuery SORTER
How do you paste into criteria?

From there I would like to do a Word Mail Merge by having VBA open a document in Word, then activate the Merge to a New Document instruction.
