Suppress a section on the basis of two conditions

Hi;

I am trying to supress a section but to do that two conditions has to be satisfied. I am not able to give the If statement with two conditions

I tried the below but it does not works out

if {spOrderAck;1.name} = 'XXXXXXX' and InStr (1,{spOrderAck;1.description} ,'TOYS' )=1

then

    true

else

    false

Please help me to know hwo to sort this out.
