FactoryTalk View Studio - Animation Help

I am having trouble with the expression editor setting up some colour change animation.

I have a bool tag and an int tag.

I will have four possible colours displayed, based on the value of the Int tag. But only if the bool tag is true. If the bool tag is false I do not want any colour change on my object.

If BOOL_TAG = True, I would like the INT_TAG to determine the colour.
If BOOL_TAG = False, then I do not want any colour change.

Am struggling getting an expression to work for this, any advice would be appreciated.
thanks

Set up values and colors then use the expression
If {[PLC]bool_tag} == 1 Then {[PLC]int_tag} Else 0

If not {bool_tag} then 0 else {int_tag}
