Using Len() in the script on a field with a number as a name

[hopkinsc]

Hi all, 

Is there a work around for using the LEN() function in the script on a field that has a numeric name?

Basically, i have a field with the name of 201901, and if i try and use an IF(LEN()) in the script it returns the wrong result but if i change the field name to be 'FIELD' then the if statement returns the correct result. 

Any ideas?

I have attached an example.

Use square brackets around the field name

If(Len([201901]) > 0, 'Yes', 'No') as Complete
