In order for this to work, you need to add the Parameter to the context of a worksheet. Trying to pass a URL parameter on simply a TEXT box from the DASHBOARD selection will not work....
So you have two option.
1. Create a calculated field that resembles you TEXT box and put it into a worksheet.
'My Start Parameter: ' + STR([Start])
Create a Calculated field that simply references the Start Parameter. And place that onto the Detail shelf of a Worksheet
Test Calc =>
Place that sheet on your dashboard as a floating object. And change the Size to w 1px, and h 1px.
This will make the sheet "Disappear" from the Dashboard, but since it is still in a Worksheet, you can still pass the parameter values in....
Either method works. But the thing to remember is the Parameter has to be in the context of a Worksheet on the Dashboard, in order for the URL parameters to work.
Just wanted to check back and see if this was helpful to you.
Let me know if you have any questions.
Yup, Option 1 worked like charm. Thanks a lot!!!
