I am trying to choose between values in an expression tag. Previously i have just created intermediate memory tags for this but from reading the manual this should be possible all in one step.  
I tag errors even when i use the actual value1.value

if {[.]value1} \< {[.]…/value2}:  
{[.]value1}+{[.]…/value2}  
else:  
{[.]…/value1}

Any help is appreciated.  
Thanks!

So, something like this: `if({[.]value1} < {[.]../value2}, {[.]value1}+{[.]../value2}, {[.]../value1})`
