Hello all,
Not sure if this is Robofab or Robofont related:
When I try to run this script (grabbed from robofab.com):
```
# robothon 2009
# interpolate two glyphs in the same font a bunch of times
from robofab.world import CurrentFont
f = CurrentFont()
for i in range(0, 10):
    factor = i*.1
    name = "result_%f"%factor
    print "interpolating", name
    f[name].interpolate(factor, f["A"], f["B"])
f.update()
```
I get this error:
interpolating result_0.000000 Traceback (most recent call last): File "", line 9, in File "lib/fontObjects/robofabWrapper.pyc", line 3173, in __getitem__ File "lib/fontObjects/robofabWrapper.pyc", line 3180, in getGlyph RoboFontError: Glyph result_0.000000 not in font.

Any idea why? Since it says “Robofont Error”… I might as well ask here :)

you are asking the font for a glyph that doesnt exist
```
# robothon 2009
# interpolate two glyphs in the same font a bunch of times
from robofab.world import CurrentFont
f = CurrentFont()
for i in range(0, 10):
    factor = i*.1
    name = "result_%f"%factor
    print "interpolating", name

    # create a new glyph
    f.newGlyph(name, clear=True)

    f[name].interpolate(factor, f["A"], f["B"])
f.update()
```
good luck
