DEAR ALL

Can you pls give me how to write the INDEX AND MATCH function so that I can
get the left value in col-D interpolated for a col-D value say 18725.

col-C col-D
0.20 18800.30
0.40 18750.00
0.60 18700.80
0.80 18650.10
1.00 18620.90
1.20 17520.80

Other options to use sort col-D in ascending and then shift the col-C to
col-E will work. But pls advice only as above bcos I have hundreds of
columns like this and dont want to go around sorting etc. The data is
entered like this and want to proceed from here. Pls help this with "INDEX
AND MATCH" function or through VB or with most appropriate way.
