JasperServer Issues..

Hello all..... I am a recent Crystal Reports Convert, so forgive me for i know not what I do........

 

Ok so this is what I am trying to accomplish.  I have one report that I want to support multiple tables.  I want to be able to let the user select the tables at run time.   My SQL statement looks like this:

SELECT
*
FROM
$P{store}
WHERE
value_char != ''  AND server_time >= $P{Start} AND server_time <= $P{End}

order by cashier, value_char,server_time

 

 

It was working correcly before i tried to get fancy with the "$P{store}" in the from part.  
 

Am I smoking crack thinking that I can accomplish this?

 

Thank you in advance for reading my request.
