    Posted: 23 Jul 2012 at 12:53am
Hi
 
Using Crystal XI I want to give the end user the option to leave multiple parameters blank for example
 
supplier = {Supplier?}
 
or group = {Group?}
 
or family = {Family?}
 
or part = {Part?}
 
All parameters allow multiple values - and I want only one of them selected at a a time for example supplier = {Supplier?} ignore all others
 
Any help would be great

When I had to do something similar, I had an overriding parameter asking which selection the user wanted to use.  On the basis of the answer to that, I used conditions in the  record selection to pick the right parameter detail. I had a default for all of them, so it didn't matter if they weren't used.
So {?selection} is Supplier, Group, Family, Part
and 
 If {?selection} = 'Supplier' then xxx = {?Supplier}
else if  {?selection} = ' Group'  then  etc....

Thanks I can see your logic but am missing something in my execution!
 
My selection is as here:
 
{ainvdet.layout_section} = "D" and
{ainvhead.salesman} startswith ["87", "86", "80", "75", "70", "69", "66"] and
{ainvdet.invoice_date} = {?Date} and
{salesman.name} like "*Tele*" and
if {?Selection} = "Group" then {ainvdet.product_group} = {?Group}
else if {?Selection} = "Family" then {stock.price_family} = {?Family}
else if {?Selection} = "Supplier" then {stock.main_supplier} = {?Supplier}
else if {?Selection} = "Parts" then {ainvdet.part} = {?Parts}

I get the choice of selection to start but when I don't enter a value in the unused parameters I still get asked for a value?
 
Have I got the wrong end of the stick?

Sorry
 
I had not added a default value into each parameter
 
This has worked now - Thanks for all your helpSmile

As a footnote.....
 
Is there anyway to make the default value blank so the user doesn not see it?
