Hi,
 
I have a parameter that allows for multiple values. Can I display all the chosen values in a page header?
 
Thanks
Joe

you can use the join() function
e.g.
join({?Param},', ')

sorry got another ?? on this which would help with other thing also.
What if the paramter was dynamic and you wanted to use the description instead of the value?

you would have to write a loop to convert values to the strings and then join that array.

I haven't tried it, but I think you could just add an ToText function.

join(ToText({?Param}),', ')

Nope. since the param allows for multiple values it is an array and you have to subscript it to use the totext. It will appear to work if only one value is selected but breaks as soon as more than one is used.
