Corrected Date for blood draw?

Ok, so I've been trying to be beyond anal about this whole process, and I can't believe that I went and made this stupid mistake!

I printed the Third Country Vet Certificate (EC 998) from Defra's website (instead of using the one in the Pets thread above). It is 3 pages long, due to formatting. On the bottom of the 1st page is where you have to enter the date of the blood draw. I messed up and put the wrong date - made it look like the blood draw was in April and it was really in Feb. (don't ask me how I did this ). Well, I just had my vet cross out the date and write in the correct one (in the correct format) and initial it. Should I go ahead and completely re-do this page instead, with the correct date? I filled this page in anyways, before going to the vet.

If it helps any, my stepsister is actually my vet, and she doesn't mind looking over it again if I re-do it..and I wouldn't change the date on the 2nd page where she signed it. As a funny aside, she was really worried about making sure she put the date in the correct format, when we realized today was July 7, making it 7/7/11 no matter which way she wrote it! 

Or will I be ok if I just leave it as is, with the incorrect date scored out?

I would re-do it, just to be safe. If it's your stepsister and it's not a big deal, why risk it?

I was thinking the same thing last night. I just wasn't sure if that would be considered cheating or something. Since there's nothing for the vet to sign on that page, I don't see why I can't re-do it. I just can't believe I made the mistake, after how careful I was being on filling it out!   

It's not cheating, assuming all the information is still the same (i.e. you're not pretending something happened on a date it didn't). You're just correcting a typo, basically.
