    Don't disturb me if you have not developed similar app in past. We are looking for an app which can broadcast cricket live streaming through Zoom channel directly from stadium or any API of Betfair or World7.com. It should be similar to web app. It should show faster results than tv or other live streaming apps. There is atleast one ball difference between actual game on stadium and live broadcast on tv or mobile. There are some apps like Bullet24, Taj777 which shows live streaming through zoom i.d only when live match starts. They stream through some API which is perhaps sourced directly from stadium. You will have to arrange Api yourself. We will pay for that. Source code of the app will be our property.

    Color Picker JS in FileMaker 6 天 left

    Demo file attached for your inspection. Basically it should work as it is from the WolfPack from Richard Carlton. However, for the life of me, I cannot see how it works. Click the colored rectanlgle, look at the range of colors, and pick a colour., Yet, amazingly, despite having done all of that and can see the Perform Javascript in the JS code, it cannot grab the selected color and transfer it to the Get ( ScriptParameter ) in FileMaker. Huh? I am using the latest FileMaker Pro 19 app. This project is suited to someone with good JS programming skills. Connection to FileMaker is already there and should work. Happy freelancing with this one!
