Ifelse statement syntax multiple conditions is broken

I am having some trouble with a nested ifelse statement. I have the following code written. It should force a TRUE or FALSE but I am getting some NAs. Can you help me figure out where its broken?

data looks something like...

Name<- c(Jon,Jim,Jake,Jess,Jill,Jay,Jason)
LinkFlag<- c( NA,  NA,  NA,  NA,  NA, NA, NA)
1<- c(1.0, 1.0, 1.0, 1.0, 1.0, 1.0, 1.0)
2<- c(2.5,  NA,  NA,  NA,  NA, 3.0,  NA)

spread_wide<-c(Name,LinkFlag,1,2)

The intended Result is that there are no NAs

sw_RESULTS$EvalSeq1to2<-ifelse(spread_wide$`1` == 99, TRUE, 
                   ifelse(spread_wide$`1` == (spread_wide$`2`-1), TRUE,  
                           ifelse(is.na(spread_wide$`2`),TRUE,   
                                       ifelse(spread_wide$`2` ==99,TRUE,
                                            ifelse(spread_wide$`1`== (spread_wide$`2`-0.5),TRUE, 
                                                       ifelse(spread_wide$`1` == spread_wide$`2`, TRUE,  
                                                                   ifelse(spread_wide$`LinkFlag`=='FlagforSkip", TRUE,
                                                                                                                                 FALSE)))))))
