I have a large lump on my head from banging it repeatedly on the desk from frustration!!!!!

 

I hope I get get some relife here.....

 

I am trying to handle a ? variable input to present 'All Channels' if the % is selected from the drop down box.

 

I am using Crystal 10.

 

I have three parameters two fro dates and one of string, the string can be channels names or to assist in getting mutiple channels returned allow the users to select "%", what I would like to do is display "All Channels" when this is selected, I have tried all manner of formulae but none have been successful.

 

The parameter name is {?Channel}

 

I have tried so many permutations I feel embarassed at offering a code solution here.
