What's wrong with convert function in where clause?

I have the query shown below. The "convert(smallmoney,newvalue)" works fine in the select statement, but when I put it in the where clause I get the error:

"Select Failed: 293 Cannot convert char value to smallmoney. The char value has incorrect syntax."

What's am I doing wrong?

select top 10 c.memberId, m.memberName, convert(smallmoney,newvalue)
from changeLog c
join members m on m.memberId = c.memberId
join members a on a.memberType = 'ALT' and a.retireeId = m.memberId
where keyFieldExtra like 'COLA%' and year(changeTime) >= 2014
and convert(smallmoney,newValue) > convert(smallmoney,0.03)

Select all Open in new window

I've also tried without the "convert(smallmoney,0.03)" in the where clause.
