i hv a worksheet which requires the user to key in values in cells B4 - B9.
values in the same worksheet of Cells C4-C9 and D4-D9 are computed based on the input values from B4-B9.

example C4 = 0.5 * B4
C5 = 0.6 * B5 etc

is there any way to protect the values of C4-C9 and D4-D9 such that it disallows the user from changing their values? i only wan the user to be able to change the values in B4-B9.

pls advise
