The style prob is fixed. thank you so much luo. I deleted the </div> some time ago because the html editor showed it as red color, therefore I thought it was redundant. I will add a comment to remind myself not to delete it again. Also the tag has to be moved after the [wpv-filter-end] tag (line 69), otherwise the html will be broken (see attached screen shot)
I was checking if the filter works probably. Sadly, something else seems to be broken which used to be working.
Filters with problems:
投資預算(field="wpcf-selling-price"), 利潤(field="wpcf-profit"), 面積(wpcf-store-size-sqft).
What problem:
the filters cannot correctly filter according to its value.
for example, when you choose the default option (which should return all results), it would only show 6 posts (out of 7), skipped the one with same value as others (selling price 280000).
then you choose selling price below $250,000, the form shows 6 posts too. there is only one post with selling price below $250,000 which is $150,000. it seems to me that the filter form behaves as if it shows results greater than the lower bound of the filter option. for example, for filter option of value 1-250,000 it shows posts with value greater than 1 instead of between 1 and 250,000.
To achieve the above range filter function, a custom code snippet has been added in toolset setting. please refer to the following link

Again, many thanks for your help.
