Ciao!

Why in the “lblCompMese” (last row in the block) I have the **NaN** result?

Grazie

“lblCompOrario” comes from Google table, column set as “Euro”  
“txtOre” is a label on the screen

I think you are evaluating text in a block that is meant for numbers only.

Thankyou. I resolved setting the column in Google drive as a number instead a currency…
