As responded in your earlier posting

Use ISERROR to mask in CF ..
Try it like this, to apply it all at one go:

Select the entire col B (B1 active)
Click Format Conditional Formatting
Under Condition 1, make the settings as:
Formula is: =ISERROR(B1)
Format the font color as white, Ok out

Note: The steps above assume you want to do it in col B
If you're doing it in similarly in col E,
use: =ISERROR(E1)

[The CF formula is always applied for the active cell within the selection]

I have copied a formula on a ledger for Purchase Orders. As I place an order
into a worksheet the information automatically fills on the ledger (separate
sheet). The cells for which there has not been a purchase order entered yet
I am getting a #REF! error. Basically I have a sheet full of these. I tried
to do conditional formatting to white out this error but not luck. I am
wanting nothing to show in the unused blanks until a PO has been entered.
Any help with this would be appreciated.
