VBA feed form values into a report query

Hi Experts,

I utilize Allen Browne's form filter code below which works great, however, I would like to apply the same concept to a report instead.  i.e. the form's filters feed a query that the report is based on, but the open event of the report collects the form filter values instead of directly referring to the form filters in the query.  

I decided to try this route as I was struggling with putting the date filters directly in the report query when there were null values or between two date values....i.e. the form code handles dates as follows, but I want the report to handle dates in the same way:

Both dates      = only dates between (both inclusive)
Start date only = all dates from this one onwards
End date only   = all dates up to (and including this one)

The code below gets stuck at the end (the part I tried to figure out) which is:
Me.RecordSource = "SELECT * FROM q_FILTER_0_Months_Main_Report WHERE strWhere"

The message that pops up is 'Enter Parameter value:  strWhere

Conceptually, I have no idea how to fix this.  

Thanks in advance for any help!
