Parameter is missing a value ssrs 2008

Question

I have a parameter of integer datatype which is hidden. When i run the report, report gives me an error

Parameter X is missing a value

Answer 1

First of all,

Check that parameter's - Available Values by going to report parameters properties.

It must not be specified any values. So we should set it as None

Second work around is,

Just add a blank space at Specify values - in Default values inside report parameters properties.

This will surely work. Hope it will save your time.
