Visual Integrator Export Automation

I would like to automate some Visual Integrator Exports.  However, I need to use the Select Tab to make sure each time the export runs the correct records are selected.

I found the following formula helpful on the Sage Knowledgebase...and it works based on date.  The formula below grabs the prior day's "stuff:"

EVS("DTE(JUL(day)-1)")

In my case however, I want to select based on month.  In other words, on May 1st I would like to have my export grab all of April's "stuff."  I have tried the following with no luck:

EVS("DTE(JUL(month)-1)")

EVS("DTE(JUL(mnth)-1)")

EVS("DTE(JUL(mth)-1)")

Anyone know how to grab a month's worth of data?

Thanks!
