Hi @kateeba,
First, kindly note that in composites that use “Only base price” pricing method, the subtotal and total prices won’t change anyhow. It’s fixed by the nature of that pricing method.
For other composites that use the “Include/ Exclude base price” option, please check WPClever >> Composite Products >> Change price if the chosen option is “Yes”.
Then, check the plugin setting to see if you have chosen “Yes” for the “Change price” option or not. https://prnt.sc/13ynn66
This settings will help change the main product’s price based on the changes in prices of selected variations in a grouped products. This uses Javascript to change the main product’s price to it depends heavily on theme’s HTML. If the price doesn’t change when this option is enabled, please contact us and we can help you adjust the JS file.
Regards,
