Load .biff table error

[#1]

I got an error when loading tables(Headline and Trades) from my exel file. The error is "Cannot locate table in BIFF file.."

Below is my script:

Load A,

B,
C,

D

FROM

(biff. embedded labels, table is Headline$);

Load A,

B,
X,,

Z

FROM

(biff. embedded labels, table is Trades$);

Any good suggestion please to sort this issue?
