UMvC3 Combo Troubles

As you can see by the title, I’m having trouble connecting hits together. >.< Here’s an example:
For some reason, I cannot get the S.L to connect after Trish’s dive kick. Same goes for Spencer when I try to zip line diagonally in the middle of an air combo. The opponent always techs out and its frustrating.

Another problem I have is…well I’ll show you.
After Strider’s diving Excalibur, it only allows me to get 1 extra air hit in before the opponent techs out, so I cant continue the combo.

If anyone has any advice please tell me. This happens to me with every character so I know I’m doing something wrong.

If you don’t get a response here, you might have better luck posting those in the character specific sections.

It’s ok, I figured it out. It was just the timing of my attacks. I was doing them too fast.
