using IF(ISERROR) statements with true/false outcome in an IF statement

Hello and Greetings,

I have two formulas:

=IF(ISERROR(VLOOKUP(D6,'SKU list'!J:J,1,FALSE)),FALSE,TRUE)

=IF(ISERROR(VLOOKUP(D196,CTO!A:A,1,FALSE)),FALSE,TRUE)

Both work perfectly and return "false" for items not in the referenced lists.

What I want to do is put them together in a new IF statement that says:

If (cell reference)="Accessories", use stmt 1, otherwise use stmt 2.

I did this but it doesn't work:

=IF(FT2="Accessories",(IF(ISERROR(VLOOKUP(D2,'SKU list'!J:J,1,FALSE)),FALSE,TRUE),(IF(ISERROR(VLOOKUP(D178,CTO!A:A,1,FALSE)),FALSE,TRUE))))

The error says one of the values is the wrong data type.

Any ideas?

Thanks!
