I have an ANOVA table and need to find the value for F. Does anyone know what that is?

$F = \frac {MST}{MSE}$

MST is the mean square (treatment)
MSE is the mean square (error)

$MST =\frac {SST}{DFT }$

$MSE = \frac {SSE}{DFE}$

SST = sum of squares (treatment)
SSE = sum of squares (error)
DFT = degrees of freedom (treatment)
DFE = degrees of freedom (error)

Does that help you?

thanks!!
