I'm trying to use Write to Excel Worksheet -> Value to Write ->

=CONCATENATE("DELETE ",TEXTAFTER(CELL("filename",$A$1),"]")," WHERE ",$A$1," = '",INDIRECT("A" & ROW()), "' AND ",$DB$1,"= '",INDIRECT("B" & ROW()), "' ;")

but I received this error:

Unexpected characters. Characters are used in the formula in an unexpected way. Expected operator. We expect an operator such as +, *, or & at this point in the formula.

Please advise!
