I made two project paramters as below
Gas Refrigerant Connection Diameter
Gas Line Radius
Gas Line Radius is actually a the radius of my pipe connection in my drawing which I added a parameter to using "DI"
Why I am getting the attached error?
Your help is greatly appreciated ๐

That's peculiar. The parentheses are not causing the issue here; you can have "stand-alone" parentheses that enclose a single Parameter, but you don't need them; they are purely extraneous.
By your image, the Parameter names appear to be identical. Try highlighting the Parameter name for "Gas Refrigerant Connection Diameter", copying to clipboard (CTRL+C), and then pasting into the formula field for "Gas Line Radius" (CTRL+V). If this still returns the error, please post the file here.
Unfortunately the problem is non of above....I also tried this for other parameters like Liq line and drain line and same error message...plz see the family file attached

You can reference Shared Parameters in formulas freely; that's not the issue, either. There is something wrong with the Shared Parameter's Name; there is somehow a space at the end of the name which is causing the error. If you created the Parameter through the Revit interface, this shouldn't have been allowed, so was this Shared Parameter created some other way?
You can fix this, but you'll have to open and modify all of your Families that contain it. Find your Shared Parameters File (.txt) and open it. Find this Parameter in the list and manually delete the rouge space after it's name. Save it, and now you have to go to all of your Families, remove the "bad" parameter and re-add the corrected one.
Edit:
This is a big mess, since now I see that there are many Shared Parameters that have a space at the end of their name. These should all be fixed, which is no easy task (except that you have that new add-in to help! ). Here as the ones I noticed in the atached Family:
Operating Voltage
Maximum Current/Circuit Breaker Size
Frequency
Total Cooling Capacity @ Design Ambient Conditions
Sensible Cooling Capacity @ Design Ambient Conditions
Nominal Total Cooling Capacity
Nominal Sensible Cooling Capacity
Nominal Heating Capacity
Heating Capacity @ Design Ambient Conditions
Designed Total Cooling Capacity
Designed Sensible Cooling Capacity
Nominal Airflow
Liquid Refrigerant Connection Diameter
Gas Refrigerant Connection Diameter
Drain Connection Diameter
Supply Price
Installation Price
Also, avoid using parentheses and other operational characters ( ) - + < > , / in your Parameter Names. It makes it impossible to reference them formulas.

Thanks Guys
It's all fixed now...:)
And yes Corey...I used that magic addon to save a bit of time
The problem was that space....I didn't know a space at the end is so important
Actually what I have done was I had all the parameter units in the parameter name for my schedules to look different then I decided to remove all the units like (mm) by opening my shared parameters file and deleting them...That space must have been left then..
