try this:

1) Instead of a Memory variable in the form, Make it a property of the form
..Form...Property ( give it a name ie myProperty)
2) Set the property in the other tab ( you can make blank or asign it a value )

3) inside of your procedure in the menu:

  *** catch the property and put it in a variable here
  lcPropertyToUpdate = FormName.myProperty
  ** do whatever you want to do with the property
  lcPropertyToUpdate = lcPropertyToUpdate + 'Whatever you want to do'
  ** send the new value back
  FormName.myProperty = lcPropertyToUpdate

I believe that will be a start.
