Simple VB query

This should be an easy one to solve.

In my VB macro code, I want to make a check on a cell's entry, but my mind just isn't working tonight.

If Cell B4 = 1, then I want my VB code to check this.

So I want my code to do this:

If B4 = 1 Then
some code
some code
some code
End If

But what do I put after the 'If' statement to make the check? I know that the code above doesn't work, but do I have to put something like:

"If ActiveWorkbook.B4=1 Then..."

Or something similar?

Basically, what do I have to put in the If statement for the code to check the contents of cell B4???

Thanks.

sheets("sheet1").select ' the sheet where you have to check for criteria.

if range("B4").value=1 then

' your code

end if

Crikey, I knew it was simple!

Of course, thanks very much. I can't believe it was so simple.
