Staff Scheduler.....can't quite get it right

Ok excel gurus I need some help since I've about exhaused the base of what I know how to do/have used from other sheets I have/ and or can figure out for myself.

I'm trying to update our staff scheduler to be more comprehensive and help with managing labor costs/budget. I finally figured out how to deduct meal periods using a formula from a scheduler that I had at a different company I think it may be a complicated way to get what I want but it works. (If there is an "X" in the K33:K40 range then it will decuct a meal period of either 30min or 1 hour depending on where they are working)If there is a simpler way I would love to hear it.

Now I am trying to figure out how to make my sheet calculate hours based on shifts assigned ( we schedule using a number system as shift times may fluctuate based on our volumn)

I need to be able to count each occurence of a shift number, then multiply it by the number of hours in the shift for each week to give me a total number of hours. The schedule is a 2 week schedule but i need each week to calculate separately(easy enough to do transferring the formlua and changing the ranges). I've also been trying to unsuccesfully only calculate if there is a name on the schedule in the name slot

This is what I was trying to use
In Cell S7
=IF($b7="","",SUM(COUNTIF($d7:$j7,1)*$j$33)+SUM(COUNTIF($d7:$j7,2)*$j$34)+SUM(COUNTIF($d7:$j7,3)*$j$35)+SUM(COUNTIF($d7:$j7,4)*$j$36)+SUM(COUNTIF($d7:$j7,5)*$j$37)+SUM(COUNTIF($d7:$j7,6)*$j$38)+SUM(COUNTIF($d7:$j7,7)*$j$39)+SUM(COUNTIF($d7:$j7,8)*$j$40))))

Which worked great if there was hours entereed for each shift position. The problem is I am not always able to run every shift all of the time and if any of the J33:J40 range is blank then I get a "#VALUE" error.

I tried to modify my formula to a SUM(IF(COUTIF($D7:$J7,1)*$J$33>0,0)) ...etc but that didn't work either. So I've reached the end of what I know how to do/ can figure out on my own

Does anyone have any suggestions, or helpful tips...that will help me accomplish this.

I have attached the file I've been working with for reference
