Increment local variable's value on button click

Question

Reactive

New to OutSystems

Application Type

Reactive

I am new to Outsystem and learning it.

I just can't understand on button click how can I increment the local variable's value.

For your reference, I was going through Courses. And in that, i am not understanding above thing in (Demo: How to Use a If Widget ). Here they have not specified how local variable's value is changed on button click.

Thanks.

val1=val1+1

See the screenshot for reference

Hi Mahalakshmi,

Welcome to OutSystems :)

As highlighted in the below image, you missed some basic implementation. I would highly recommend you to start with the Reactive Web Application Learning Path: https://www.outsystems.com/training/paths/18/becoming-a-reactive-web-developer/

The defined screen action, i.e. decrement, is not mapped as the Button OnClick event (see the highlighted warning message)
And also, the assignment node within the decrement action flow is incorrect, i.e. it should be value = value - 1

Refer to the attached .oml file

As the Tool is very new for you, I suggest you start learning from the beginning. Follow the available online learning video courses, Documentation, Community post, webinar, Tech talks etc...

Enjoy learning :)
