Some antivirus programs or website security plugins may mistakenly flag our plugin as a potential threat because it contains certain functions or code patterns — such as eval() or dynamic code execution — that are sometimes associated with malicious scripts. However, in our case, these features are used for legitimate technical purposes, such as performing advanced calculations or supporting dynamic features within the plugin. We want to emphasize that our plugin is completely clean, safe, and has been thoroughly tested. These warnings are false positives, caused by general scanning rules that sometimes misinterpret advanced code structures as suspicious. ## Reviews ![](https://secure.gravatar.com/avatar/4cd8668911c6d219513523e8b410e74661dd0c600922bc0cafec83766373c25c? s=60&d=retro&r=g) ### 󠀁[Comprehensive support](https://wordpress.org/support/topic/comprehensive-support-3/)󠁿 [unko](https://profiles.wordpress.org/unko/) November 4, 2025 英語版ですが、日本で利用しています。 元々は、条件付きロジックを探しており、数年前 にContact Form 7 Add-on Bundle – All In Oneを導入しました。 最近、contact form7の 問い合わせに計算式を導入したくて、同バングルに同封されているContact Form 7 Cost Calculator Proを使用しました。 日本では消費税10％を、税抜き、税込みで表記します。 税抜き10％をしたかったのですが、元々あるROUND関数やFloor関数では切り捨てがうまく いきませんでした。サポートに連絡した所、すぐにROUNDDOWN関数を導入してくれて、実装 する事ができました。サポートがめちゃくちゃ早く頼りになります！お購入するならばContact Form 7 Add-on Bundle – All In Oneをおすすめします。 This is the English version, but I’m using it in Japan. Originally, I was looking for conditional logic and installed the Contact Form 7 Add-on Bundle – All In One several years ago. Recently, I wanted to add calculations to my Contact Form 7 inquiries, so I used the Contact Form 7 Cost Calculator Pro included in that bundle. In Japan, we display the 10% consumption tax separately as tax-exclusive and tax-inclusive amounts. I wanted to calculate the 10% tax-exclusive amount, but the existing ROUND and FLOOR functions didn’t handle the rounding down correctly. When I contacted support, they promptly introduced the ROUNDDOWN function, allowing me to implement it.Their support is incredibly fast and reliable!If you’re considering a purchase, I highly recommend the Contact Form 7 Add-on Bundle – All In One.
