how to ignore mouse hold on SDL2?

Problem:

i want to change my character's anymation anytime a left mouse button is clicked. If i hold the button, it keeps changing the animation, but i don't need that. I want the animation to be changed only one time. I tried to do something like this:

if (csdl_setup->GetMainEvent()->type == SDL_MOUSEBUTTONDOWN) {
        if (csdl_setup->GetMainEvent()->button.button == SDL_BUTTON_LEFT) {
                LeftMouseClicked = true;
        }
    }
    if (LeftMouseClicked == true) {
        LeftMouseClicked = false;
        bob->PlayAnimation(0, 1, 1, 1);
    }

but it doesn't work. Any ideas?

Use two sets of variables, one for if the button is held or not and the other for whether the button was pressed in the current frame.

LeftMouseClicked = false ;    //is set to false every frame

if (csdl_setup->GetMainEvent()->type == SDL_MOUSEBUTTONDOWN) {
    if (csdl_setup->GetMainEvent()->button.button == SDL_BUTTON_LEFT) {
         if( LeftMouseHeld == false ) {
             LeftMouseClicked = true ;
         }
            LeftMouseHeld = true;
    }
}
if (LeftMouseClicked == true) {
    bob->PlayAnimation(0, 1, 1, 1);
}
