Severity:
`ChoosingRam::isRamSelected` is not properly updated
Summary
ChoosingRam::isRamSelected is not properly updated when calling the function increaseValuesOfParticipants if ram is selected inside
Vulnerability Details
In increaseValuesOfParticipants when Ram is selected, the value of isRamSeleted is never updated. Whereas in the function selectRamIfNotSelected it is done
function increaseValuesOfParticipants(uint256 tokenIdOfChallenger, uint256 tokenIdOfAnyPerticipent)
public
RamIsNotSelected
{
.
.
.
if (random == 0) {
.
.
.
else if (ramNFT.getCharacteristics(tokenIdOfChallenger).isSatyavaakyah == false){
ramNFT.updateCharacteristics(tokenIdOfChallenger, true, true, true, true, true);
selectedRam = ramNFT.getCharacteristics(tokenIdOfChallenger).ram;
}
} else {
.
.
.
else if (ramNFT.getCharacteristics(tokenIdOfAnyPerticipent).isSatyavaakyah == false){
ramNFT.updateCharacteristics(tokenIdOfAnyPerticipent, true, true, true, true, true);
selectedRam = ramNFT.getCharacteristics(tokenIdOfAnyPerticipent).ram;
}
}
}
function selectRamIfNotSelected() public RamIsNotSelected OnlyOrganiser {
.
.
.
selectedRam = ramNFT.getCharacteristics(random).ram;
isRamSelected = true;
}
Impact
The program might not work as intended when handling this situation, mostly because of the isRamSelected modifier

.
.
.
else if (ramNFT.getCharacteristics(tokenIdOfChallenger).isSatyavaakyah == false){
ramNFT.updateCharacteristics(tokenIdOfChallenger, true, true, true, true, true);
selectedRam = ramNFT.getCharacteristics(tokenIdOfChallenger).ram;
+ isRamSelected = true;
}
} else {
.
.
.
else if (ramNFT.getCharacteristics(tokenIdOfAnyPerticipent).isSatyavaakyah == false){
ramNFT.updateCharacteristics(tokenIdOfAnyPerticipent, true, true, true, true, true);
selectedRam = ramNFT.getCharacteristics(tokenIdOfAnyPerticipent).ram;
