Hi Julie,
Yes, this is possible. If I have understood your scenario correctly then you currently have a field on a custom form called 'external cost' and within this field the user can choose one of the following 3 options:
- under 25,000
- between 25,000 and 100000
- greater than 100000
To achieve your requirement would need to add a calculated field to your custom form and use the below code in your calculation:
IF({external cost}='under 25,000',1,IF({external cost}='between 25,000 and 100000',2,IF({external cost}='greater than 100000',3,'')))
One thing to bear in mind . . . In the above calculation we are looking for an exact match to the field selection, so make sure that the values in the code exactly match the values in the external cost field (i.e. I noticed that you used a thousand separator in some answers but not others. If your external cost field has 'greater than 100,000', but in the calculated field you have 'greater than 100000', then Workfront wont identify it as a match and will fail to do the calculation)
Hope this helps!
Best Regards,
Rich.
