There is any way to calculate a value from text box data entry and show it in another text box?

How complex mathematical expression you want to use in the Text box? You can set an example of one of the most complex expressions?

add school grades

hi @barbosadantasvpj, I tried this in my app and didn’t have any issues with it. The calculation was performed and the value was returned correctly. [calcualte%20grade] I’ve used the exact same blocks that you have (as far as I can see anyway!) [49]

Is this what you’re looking for??

Im looking for a event o trigger when the user enter a Quantity in a textbox and unit price in another textbox automatically calculate the first one by the second one and show it in the Total textbox

¿Its that posible without press a button for the calculation?
