if elseif statement

[vk01]

hi,

 

I have a variable which should be equal to one value at a given time: like

if val1 != null

var = val1

elseif val2 != null

var = val2

elseif val3 != null

var = val3

else var = " "

end if

 

I know at a given time there will be only one value otherwise a null value.

 

How would we go about doing this?

 

thanks.

You could do it in a scriptlet or by placing conditional sections within conditional sections

 

( <condition> ? ( <condition> ? ( <condition> ? exp1 : exp2 ) : exp2 ) : exp2 )

 

etc
