big trouble with combobox/vlookup

hi there, im setting up a form and this is what i got so far,

sheet1(data) with a table from A2:K106, sheet2(form) has a scanned pic
and some formatted cells where i want my vlookups to work in, the
first 2 are formatted 5 columns by 2 rows (C7:G8,C11:G12) and the other
6 cells are 1 column by 2 rows (I7:8,I11:12,I15:16,K7:8,K11:12,K15:16).

iv used form comboboxes, control toolbox and data valadation but
nothing seems to work with the vlookups this is what iv been using

=VLOOKUP(B3,CommonName,3,FALSE)

B3 was the cell i linked the form combobox to, and thats about it i
think all the rest was trial and error, lots of error haha help!
