Issue adding a symbol after a field value

[UMDTERPS]

The following previous splunk thread works fine:

https://community.splunk.com/t5/Archive/Insert-sign-for-each-result-in-a-specific-column/m-p/149167

| eval sensor = sensor + " %"
51%

However,  if the field name has a space, it does not work:

| eval "System Outlook" = "System Outlook" + " %"
System Outlook %

I'm assuming it needs some sort of backslash escaping? (I've tried a bunch of ways). I know I can just rename it without the space, but I want to keep the space.

Any ideas?

When using field names with non standard characters, you need to use single quotes on the right hand side of the eval statement, i.e.

| eval "System Outlook" = 'System Outlook' + " %"

Perfect, that worked!

Thanks!😀
