Filter in Confiforms for Numerical Value not working

[Dhiraj Kr_ Gupta]

I have applied a filter in Confiforms Tablet View but it not working.

(Remaining: <0 AND Remaining:>-60) OR (ExtraDay: <0 AND ExtraDay:>-60)

Field name Remaining and ExtraDay are calculated field based on the date difference.

What is wrong in this formula in Confiform filter

[Alex Medved _ConfiForms_]

(Remaining:<0 AND Remaining:>-60) OR (ExtraDay:<0 AND ExtraDay:>-60)

Most probably the space is confusing the ConfiForms parser
