Help with a fomula

[Lee McKinney]

Need a formula to add (sum) a series of other calculations with a certain range.

EX:  =(M29*$M$7)+(N29*$N$7)+(O29*$O$7)+(P29*$P$7)+(Q29*$Q$7)+(R29*$R$7)+(S29*$S$7)+(T29*$T$7)+(U29*$U$7)+(V29*$V$7)+(W29*$W$7)+(X29*$X$7)+(Y29*$Y$7)+(Z29*$Z$7)........

Hi Lee,

Could be

=SUMPRODUCT($M$7:$Z$7,M29:Z29)
