There is an empty space after the price as well as the operator may not be correct: https://i.imgur.com/boHQMVN.png
The empty space is not automatic trimmed, because this field type is for strings, and whatever is entered, it is used (including spaces).
If you remove it, it will work.
I have added budget slider in my website in home page. and i am adding pricing as 1cr to 50cr. but the comma i am adding is not coming properly. as i want commas in cr as 1,00,00,000 and 50,00,00,000 please let me know how can i do this?
The commas are thousand separators – they are added after every thousand, thus 3 zeros, not 2. I’m afraid that is not possible to change in the slider.
