Iterate Databases and Delete Query
I am trying to iterate a table with database names in it, open the database, check if a query exists, if it does delete it, then import a query from the database this code is being executed from. I keep getting a compile time error on the line of
Set badqueryname = "qry_InformationMailer" and what I am trying to do with that is set the name of the query to delete. This is the error that line throws

Set when you assign a value to a simple variable type.
'Set badqueryname = "qry_InformationMailer"
badqueryname = "qry_InformationMailer"
Or, if you wish, you could use
Let instead of
Let badqueryname = "qry_InformationMailer"
But I don't see
Let used very often anymore.
Actually, in your code the value of badqueryname never changes again after you assign its value. In other words, it's being used like a constant, so you could just make it a constant.
Const badqueryname As String = "qry_InformationMailer"
One of those changes should eliminate that object required error. However, then you will encounter an error with the undeclared qry in this line ...
If qry.LoopName = badqueryname Then
Option Explicit to your module's Declarations section and then run Debug->Compile from the VB Editor's main menu.
The compiler should also complain here because l is undeclared ...
For l = LBound(myArray) To UBound(myArray)
Fix anything the compiler complains about and then run Debug->Compile again. Repeat until no more compile errors.
