# Ni allaf greu cofnod person newydd

## Pan yn yr adran bobl, rwy'n mynd i ychwanegu person newydd i'm grŵp, ac rwy'n derbyn neges gwall bod y "Defnyddiwr Eisoes yn Bodoli".

1. Mae hyn fel arfer yn digwydd pan ddefnyddir yr un e-bost sydd eisoes yn cael ei ddefnyddio gan gyfrif arall ar gyfer y cofnod person newydd.

2. Pan yn yr adran **Pobl** cliciwch **Create Person** .
3. Wrth nodi manylion yr unigolyn, er enghraifft **Enw Cyntaf** ac **Enw Diwethaf**  gwnewch yn siŵr nad yw'r **Cyfeiriad E**-**bost**  rydych chi'n ei ddefnyddio yn erbyn y cofnod newydd hwn yn cael ei ddefnyddio gyda chyfrif arall yn y grŵp.![](https://knowledge.groop.com/hs-fs/hubfs/Screenshot%202020-02-17%20at%2015.42.06.png?width=600&name=Screenshot%202020-02-17%20at%2015.42.06.png)
4. Os mae’r cofnod newydd yr ydych yn ychwanegu yn, er enghraifft  Plentyn, gallwch ychwanegu eu Enw Cyntaf ac Enw Olaf, gadewch y cyfeiriad e-bost yn wag, a chysylltwch a gwarcheidwad![](https://knowledge.groop.com/hs-fs/hubfs/Screenshot%202020-02-17%20at%2015.39.07-2.png?width=600&name=Screenshot%202020-02-17%20at%2015.39.07-2.png)
