Setting dimension color properties in Straight Chart

[#1]

I've been trying to set the color of a dimension in a straight chart. I am new to QV so I must be doing something wrong because this seems so simple.

I have a imported data from sql. One of the columns/dimensions is an integer.

I have tried to use this as the color property:

=If(age > 60, Red(), Green())

It always displays green. What have I missed. 

thanks

Never mind. I forgot that things are case sensitive.
