Do i have to redo my prayer?

[cinnamonrolls1]

Salams all, so i was praying maghrib, and i thought id forgot my first tashahud- i was praying the third one. Accidently, instead of doing my last tashahud, i started doing the prostration of forgetfullness :/ is my salah valid?
Basically i did this: prayed first two rakat, went on to third- whilst i went inro sujood i started making the duas made during the prostration of forgetfullness, and instead of doing my final tashahud, i just said salam.
Do i have to redo maghrib?

To be on the safe side, just re-do your maghrib prayers if there is still time, because the last tashahhud is an obligatory part of Salah.
