Like

"SemiBold", "Bold", "ExtraBold", "Heavy"
If your Parameter ShowSummary = True than change the Font Style to "Normal" otherwise "Bold"
Step 1)
Create Parameter ShowSummary
Data type : Boolean
Default Values, Click Add and type True (Defining default Value = True)
Create New Parameter as ShowSummary, data type Boolean
Set default value as False so by default summary value will be False
Right click on your textbox, Select Textbox Properties, Select Font, Click on the Fx button besides Bold
as per the parameter value, show font type
Now run the reports, you can see that when you select show summary = true your text box font type appears "Normal" or it will show in "Bold "
