sheet not calculating a "=index" formula that referes to a cell that has been changed by find and replace

I have a fairly large spreadsheet wherein a column of cells refers to an adjacent cell to lookup.
=INDEX(Return_value_range, MATCH(Lookup_value, Lookup_value_range, Match_type))
I then noticed that one particular value in the "Lookup_value" cells needed to be modified so I ran a Find and Replace on the column to change a text value of "00000142" to "142". After that the formula that refers to the modified cell gives a result of "#N/A" and only if I "edit" the referenced cell (not changing anything but just using F2 to access the cell contents and then pressing enter. This would be ok if there were just a few, but there are over 1000 cells that need to be recalculated. I tried to "copy special" the entire column over itself using different options none of which made any difference. Of course, I also tried just recalculating the sheet and I exited/entered Excel all to no avail. Is there anyway to get these cells to be correctly referenced?

Nope, didn't do it. It's odd because it's not the formula but the referenced cell that is the problem. Not doing anything to the formula but just using <F2><enter> on the referenced cell forces the formula to work.
Actually, however, what you said gave me an idea.
In a column three to the right of the problem text cell (say "H"), I entered the formula
I then special copied (value only) that cell over the problem cell... and it worked.
I then did the whole column and ended up with no #N/A cells. Much quicker than one-at-a-time.

Try deleting all but the top formula, then dragging the remaining formula down to fill the column.

You could select the column, then do a Find/Replace and replace all = signs with = signs. Make sure to find inside formulas, not values. That will recalculate all formulas.

Although Wayne's comment didn't do the trick, it did give me an idea on how to fix it. I figured I'd share the credit.
