Formatting Excel cells

[Sally26]

I have written a
Formula in a column, the formula is fine but how do I show the cells as blank? The formula is basically if say j4 equals10 show in the said cell yes if not no. Ive copied the formala down but its showing no in all the blank cells in the column where the rows haven't been completed?

[#2]

=IF(ISBLANK(J4),"",IF(J4=10,"Yes","No"))

[#3]

=IF(ISBLANK(J4),"",IF(J4=10,"Yes","No"))

Thank you, however I've copied the original formula into another column and it shows blank unless i type 10 or another number in, which is what i want?

When you copy to another column formula will be changed, you may check in formula bar. If fix the reference use absolute references ($J4)
