Grasshopper Scripts For Reading Excel

Hello, everyone

Good evening!!

I would like to ask you about grasshopper scripts. I want to use the data from excel and would like to join the parameters in order to edit the parameters from the excel directly.

I joined some scripts like the picture that I attached. But the problem is that some numbers from the excel work well to change the parameters. But sometimes, I got error and I cannot edit from excel. I did not use the panel directly to join. I don`t know how could I solve? If you have a good idea, could you explain it to me?

Have a nice day, everyone!!
