I would like to have a criteria in a query that would take todays date and subtract a number of days from a control on a form. I found a dateadd function but no subtract! ie, this would pull all records in last 30 days.
Thanks!

"d"-30 etc

Try this, in the first column of your query select all records. The next column type for a field name:

DateSubtract: Date() - ([Forms]![YourFormName]![YourControlName])

Uncheck the show box, then for critera put:

< 30 (Or < 31 if you want those records too).

This may be useful to others.
Use the DateAdd function but set the value to '-'.
eg.
DateAdd("d", -3, Date)
this will subtract 3 days from todays date

It will not you've forgotten the parenthesis after date should be DateAdd("d", -3, Date())

with or without parenthesis, Garswoods' code will still run.
