              //update Object permission for Opportunity 
                PermissionSet ps =[select id,ProfileId,SystemModstamp,UserLicenseId FROM PermissionSet where id='parameterValue '];

Are you getting an error? or is it just not working as you expect. If it is the latter, perhaps you can try logging the value in the 'selectedValue' variable, and see if it is indeed 'readselected'.

Hi Bhaskar,

Please change your query as shown below and your code will work correctly:
  
PermissionSet ps =[select id,ProfileId,SystemModstamp,UserLicenseId FROM PermissionSet where id=: parameterValue];

Here, "parameterValue" is a variable, so you have to use =: syntax for it in SOQL query.

Hope it helps you.

Thanks,
Prashant
