How to hide an error in formula or display null while it's not properly feeded?

[kdev]

I have a cell with a formula that do some calculations based on other cells values.
The problem is that I want to copy the formula to remaining cells that are not yet populated, and I’m getting this error on cells that contain the formula:

#DIV/0!

This error is normal because until I add new values, it will trigger a division by 0.
How can I hide this error or add a maybe add an if statement that checks “if cell is empty then don’t apply the calculation”?

Here is the formula:

=ROUND(B14*1/(G14*C14/100),6)

Where B14, G14 and C14 are empty by default but will receive values in the future.

Thank you.

“Hide” by returning the empty string: =IFERROR(ProbablyErroneousExpression;"")

Or: =IFERROR(ProbablyErroneousExpression;AlternativeExpression).
If AlternativeExpression returns an error , it will show!

[The globally accepted parameter (“function”) separator is the semicolon.]

Big thanks, it’s this!
