you can use the inequality operators or the ... ellipsis, but not both in the same find criteria. (The rules for what you can specify manually and what you can put into a request using set field are the same.)
What you specify doesn't really make sense to me.
What do you expect to find with that criteria?
Do you want to find all records where the field's value is less than or equal to the first number or greater than or equal to the second?
That can be done, but not with the criteria shown.
See this thread for series of scripted find examples using Set FIeld: Scripted Find Examples
I'm searching for a range of Lengths in a found set. In my post I gave a single example, >=90" and <=108".
Which can be done but not with the criteria specified in your example. And apologies, I looked this one over in a hurry and didn't notice that you'd specified values for the global fields.
There are two basic approaches that will find the records without listing all possible values from 90 - 108 (which even then wouldn't work if you have possible values that are not integers such as 95.6.)
Method 1. Use two find requests
Specify >= Minimum value in the first request
Specify > maximum value in the second request
Make the second request an "omit" request.
This can be a scripted or manual find.
Method 2: Perform a find and then constrain the found set.
Perform a find with the >= minimum value criteria
return to find mode, specify <= the max value but then use Constrain Found Set instead of Perform find.
