Copying from textbox to relative cell in array

Okay, I have made a dynamic hyperlink based on

HYPERLINK("#"&ADDRESS(S16,S15+2),"Click here to go to 'last case' cell"))

with S15 =

=(SUMPRODUCT((O14:O70=O5)*(COLUMN(O14:O70))))

and s16 =

=SUMPRODUCT((O14:O70=O5)*(ROW(O14:O70)))

Now, the thing is I am trying to make a textbox copy its value to the dynamically referenced cell (according to the lookup cell of O5)

This is basically person selectes a month (in the lookup cell) which reutrns that month "cell address" in a reference table. the text box would enable the person to enter in information that would go adjactive to the referenced cell 9in the table)

Any ideas?

Hi

can you please attach an example file, and include relevant code. I'm not really sure from your description of what is where....
