Can you provide a few more details such as the SAIL code for your start form, list of rule inputs, and list of process variables set as parameters?

Sure. Thanks a lot for your response.

Your variables look fine. Please also attach the SAIL (Using the code block for readability) for your other interface rules. What I imagine is happening is you have saveinto: saveinto: somewhere by accident

Your issue is here, 'expression: expression: '

There error you saw is a common error when an interface is missing a comma somewhere

Ok. Got it & Corrected. Now it has been fixed. Thanks a lot for your help.

My doubt is why it did not display this error in the interface itself?

Hi, Danny. I want to learn the Appian Development very well. Give me your suggestions in this regard. Actually I was a PHP developer. I have to work on Appian platform now. Any inputs from your end? Thanks a lot.

I recommend going to the Training tab in Community and taking multiple courses. It also helps to build simple applications in Appian to get comfortable using the platform.

Sure. I will do.
