I tried sticking the strip all the way in first, and I didn't get "Error." Whew!
Because I am wrestling with Bubbles, I was getting the blood on my fingernail, first, then trying to push in the strip, and by the time I got to the drop, I'm not sure if I was smearing it, or what, I just kept getting errors, and I didn't bother to look up what for, just kept at it til I got a result. Poor Bubbles, I am very stubborn ;-) . I am going to try and hold her more firmly and get the drop from her ear, with the strip already pushed in...we'll see how that works. Thank goodness it worked tonight.
