Hi @grarun11,

This is covered in the documentation for [using variables](https://robotframework.org/robotframework/latest/RobotFrameworkUserGuide.html#using-variables)

For your specific question would be something like this:

```python
   VAR ${giftammount} 10
   VAR ${dayofmonth} 15
   VAR ${qstring} Would you consider making an additional gift of \$${giftammount} every month ${dayofmonth}th to ?
   Log ${qstring}

```

Dave.

Hi @grarun11 ,

The first 2 lines was just to give the variables a value so this was a working example, the 3rd line is what you need for your test case, just replace the variable names with the ones you want.

Hi,

Can your precise where the values come from?

- Either from a locator in the page (with a Get Text or Attribute Value)
- From a condition that gives 10 and 15 (here I would use a corresponding table)
- If the values are totally random, then I don’t see how you can validate it’s correct if you don’t know what expect. Here the best would be to use regex or glob pattern to replace the values in the obtained variable. At least regex verifies the text, and returns the two values in the string for check.

Regards  
Charlie

15 is current date so I used now{} but 10 varies depends on the amount. I can use gettext and get that value
