Default min/max from jobs grade rate but leave blank for jobs without grade rate

Summary:

We are currently using jobs and some jobs are tied to a grade rate and some are not. We are needing to default the min/max from the grade rate on the requisition but if there is no grade rate attached then either default to zeros or left blank. We have gotten it to default but if it is left blank we are getting an error in the question block and unable to submit requisition. Has anyone seen this before?

Content (required):

This is a global client, US jobs have grade rate and some in EMEA do not.
