Formula for Radio Button, Combo Box, etc

[flashes24]

I am trying to make a formula in Lotus Designer for an end user to choose 0, 2, 4, or 6. When they click on the button another text box computes this value multiplied by 10. I can't make it work I keep getting "ERROR: Incorrect data type for operator or @function: Number expected.

Or answer this question: How do you change the value of a Radio Button, Combo Box, etc to a number value?
Thanks,

You're mixing text and number variables in your code.

The output from a radio button is text so you need to conver the text to a number by using @TextToNumber(FieldName)

So, your computed (number) field default value would be:

@If(RadioButtonFieldName="";0;@TextToNumber(RadioButtonFieldName) * 10)

This way you are generating a number output for a number field.

The first part of the @If statement above just ensures you don't get an error in your number field if the radio button value is nul

If you want the number field to re-calculate every time the radio button value changes then make sure you select the "Refresh fields on keyword change" in the properties for you radio button field.

Hope this helps!
