Help - calculation widget in form not working properly

We just got a submission for this form - $500 donation PLUS the person purchased 1 leaf.  For some reason, the total was off by the $500 and it didn't add the 3% charge.  I noticed in settings that one of the conditions is no longer working.  I don't know why as I haven't changed the form.  Can you help?

It looks like the field being used in your condition was either updated or deleted but the condition was not:

Although it looks like you have already updated your calculation instead.  I entered 500 for the donation amount and 1 leaf and the total came out to $885.80.

If this is still not working on your end, let us know and we will take another look.

hmmm....  I set this up a while ago and forgot what the condition was supposed to do!  Can you remind?  Is this why the person's submission didn't calculate correctly?

It looks like that condition was previously set up to update a the calculation field with a value.  That could have been the caused the value to update improperly depending on if the missing field was used in your calculation.  The calculation does look to be correct, I would simply delete that condition.
