If columns 2-4 have data, but columns 5-7 dont. Then call True

[HockeyDiablo]

Here is where I am going with this. But where am I going wrong? all type(2). Formula in Col8
-I'm getting tied up while trying to ensure the first 2 characters in column2 is a number "0-9"

=IF(AND([@Column2]>0,isnumber(left[@Column3],2*1)=TRUE,[@Column3],""),[@Column4]>0,[@Column5]=0,[@Column6]=0,[@Column7]=0),TRUE,FALSE)

SO heres an example:

[TABLE="width: 800"]
<tbody>[TR]
[TD="align: center"]Col2[/TD]
[TD="align: center"]Col3[/TD]
[TD="align: center"]Col4[/TD]

**I am working within a table**

=IF(AND([@Column2]>0,isnumber(left[@Column3],2*1)=TRUE,[@Column3],""),[@Column4]>0,[@Column5]=0,[@Column6]=0,[@Column7]=0),TRUE,FALSE)
=IF(AND([@Column2]>0,(ISNUMBER(LEFT([@Column3],2)*1)=TRUE),[@Column4]>0,[@Column5]=0,[@Column6]=0,[@Column7]=0),TRUE,FALSE)

Got it. Thanks
