    Color Picker JS in FileMaker 6 dias 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!
