Increment the text box number?

In Construct 3, I have a text box containing a number, which is 40, and it's associated with a panel.

Every time the player clicks the panel, the value in the text box should increase by 50%.

How do I do this?

EX:

If the text box contains 40, and I click the panel, the value should increase by 50%, which makes it 60.

If it's 60, it should increase to 90.

For 90, it should increase to 135.

It's better to use a variable - increase the variable and set the text to that variable.

Without a variable you'll need to convert the text to number and back.

Textbox set text to str(int(self.text)*1.5)

or use float() expression instead of int() if you need decimals.

Thank you
