st: ATT greater than one

Dear Statalist,
I'm using psmatch2 (user-written software) to find the ATT of a welfare programme. In some of my results, the ATT is coming up in extremely high numbers. The standard errors are also really high.
Does this mean that I've done something wrong? How would I interpret this?
I know that ATT should be interpreted as percentage points, i.e. an ATT of 0.67 would mean an increase of 6.7 percentage points, but what about an ATT of 1482.47, with a standard error of 1497.69?
Many thanks,
Isobel Williams
