Thank you but it should work with if condition .let say if condition say's yes than only that tdl should work

 

You can use "Option" or "Switch" if you want to execute code only if the condition is true.

Code:

[#Part: VTYP Behaviour]
Add : Option : My VTYP Behaviour : <Your Condition>
[!Part : MyVTYP Behaviour]
Add:Line:At End:VTYP_ADD
