Hi everyone. I am using thunkable for the first time. Was setting up a fuel log calculator. I have 3 to 4 textboxes where the quantities will be entered by the user and i wanted to put a if logic in case any of the textboxes was empty. I am not sure what specific blocks to use as i see the if/else logic but specifics how do i clip in to it that if any of the text boxes are left empty then turn the textbox border to red? Please help

hi,  
you have to use the text component  
step one go to the text section of blocks

step two use this component colored in red
