Greetings to you!
You should make sure you don't have any null elements. The real problem lies in these lines:
for(account a:accounts){ selectoption op = new selectoption (a.Phone,a.name); options.add(op); }If the a.Phone or a.name field is NULL, options is added with NULL.
So change those lines as below:
for(account a:accounts){ if(a.Phone!=null && a.Name!=null){ selectoption op = new selectoption (a.Phone,a.name); options.add(op); } }I hope it helps you.
Kindly let me know if it helps you and close your query by marking it as solved so that it can help others in the future. It will help to keep this community clean.
