excel question

I am doing a label merge to keep track of years that customers have purchased different items. There are 30 items. Some customers have purchased 1, some have 30. I want the la

I want it to say on the label "X has purchased A for _ years", "X has purchased B for _ years, etc"


in one column there are numbers, but not every cell has a number because not every customer has purchased that item.

in the next column I used:

=IF(ISBLANK(I10), "","has purchased X " & I10 & " years,") so that the cell will only populate with the wording if there is a number next to it.

the problem is that now there are cells that say "blah blah 1 years"

I tried to use the find/replace to find "1 years" and replace with "1 year" but it won't let me.

Anyone have any ideas?
