craftgrrl | more knitting frustration...

[edit: thanks so much!!! after someone said it does add up correctly i went back and figured out that i am stupid and have been passing my slipped stich back over onto the left needle instead of dropping it entirely....OOPS! yes i am a dumb beginning knitter, lol, thanks, red_jenn!]

>_< ARGH! this is an appeal to all you knit-gurus out there...help please???

please tell me if i'm counting right (i think something is wrong with the pattern; if there isnt' something wrong with it maybe something's just wrong with me haha)

when a pattern says...(i'm doing three pattern repeats...)

Row 5 *P 5, (k 1, p 1) twice, k 1, p 5; rep from *.
    [each pattern repeat uses 15 stitches and ends up with 15 stitches in it]
Row 6 *K 1, yo, k 3, yo, slip1-k2tog-psso, p 1, k3tog, yo, k 3, yo, k 1; rep from *.
    [each repeat uses 14 stitches and ends up with 15...but this is a problem because it gives me an unused stitch for each pattern repeat         and that means i have 3 extra stitches hanging out there at the end of the row!!]]
Row 7 *P 7, k 1, p 7; rep from *.
    [ meaning I can't do row 7, since now the # of stitches is all messed up...]

How can I modify the pattern in row 6 so that it uses 15 stitches and ends up with 15 stitches? (Unless I'm doing something wrong with my knitting and am using one less stitch than I should be in each repeat...if I've counted wrong, please tell me).

Here is a link to the original pattern, if that's helpful:

i'm sorry this isn't a picture post...i could draw you a picture of my frustration but i don't know how much that would help...

thanks so much...~!
