Calculate value of variable using parameter default value and an on-scree object variable value

I have a parameter (Invoice Amount), which has a default value of 1000. I have a variable (discount), whose value I get from an on-screen object. I need to calculate the value of Amount (which is ano...

    See attached screenshots.  I wrote the total into a remarks field that's text so you can see the layout.  If you still aren't seeing the correct calculations, put log messages at the top and display each one of the variables so you can see what the values are at the beginning.

If Discount and Amount are project variables, then use:

Project.Variables.Amount = aqConvert.StrToInt(InvoiceAmount) - aqConvert.StrToInt(Project.Variables.Discount)

 

If they are local variables, then use:

Amount = aqConvert.StrToInt(InvoiceAmount) - aqConvert.StrToInt(Discount)

 

To set the on-screen value, use

NameOfObjectToSet.set_text(Project.Variables.Amount)

or

NameOfObjectToSet.set_text(Amount)

Thanks Marsha.

 

It still is not giving me the calculated value, and does not enter any value into the field.

Discount_Amount and Bank_Amount are local variables.

But, Invoice Amount is a parameter, local to the test.

 

I have it now as:

Run Code Snippet                     Bank_Amnt = aqConvert.StrToInt(Invoice_Amount) - aqConvert.StrToInt(Discount_Amount)

Object           SetText                    KeywordTests.My_Test.Variables.Bank_Amnt (also tried it as just Bank_Amnt)

      Marsha, what you have described seems to be the right solution and I have my test steps exactly like yours. However, it is still giving me a null or 0 as calculated result. When I log it, it returns empty message. On my screen, it seems to enter a null value.

      I've attached the screenshot of the log.

        See attached screenshot.  Use messages like this right before the calculation and right after to display the variables and parameter so we can debug.
