Referencing expression in table

Hi all, I have a question on referencing issue.
I write my expressions in a table and then I want to reference them in other node but it failed.

This shows how I did it.
I wonder how to reference the expression in a table?
Anyone knows the answer?
Thank you in advance!

You just have to eval() the string returned from the table:

eval(op('value_table')[1,1].val)

That’s the magic! Thank you so so much Matthew!
