Logical expression?

Hi,

I was written the statement below.

READ TABLE t_vttk_vttp INTO w_vttk_vttp WITH KEY

vbeln = t_vbuk-vbeln

tplst = c_tplst6 and

tplst = c_tplst2

tplst = c_tplst3

tplst = c_tplst4.

But iam getting the error TRSTA is not expected. when i give the sinlge stament it is not giving error.

READ TABLE t_vttk_vttp INTO w_vttk_vttp WITH KEY

vbeln = t_vbuk-vbeln

tplst = c_tplst6.

How to write the logical statment for above statement,

Regardsm
