Bex Condition says Not Complete when entering multiple parameters

Hi,

I have made a query with 7 parameters and there is only one condition with that query...

when executing the query without filling any parameter the condition is active but when i do 2 selections the conditions says not complete instead of Active.....

condition says Qty conf Between -9999 and 9999

parameter are

SPA for selc opt

validity date selc opt

material selct opt ....

when if fill the SPA with a value and the validity date the the condition does not work any more , i do have data in the query ....

also if i only fill one parameter like SPA then the condition is set to active...

Can someone tell me what is wrong or if i am missing something .. this should be a simple situation
