Conditional Formating Based On Other Cells Being Blank

Hello All - I've had trouble finding a solution for my specific issue and have attempted a variety of conditional formatting methods with little to no success.

In the attachment I am trying to force the user to fill in all the necessary fields before an end result registers. Those fields highlighted in yellow are "required" (Note: Aside from B15:16, it is really the calculation in B18 that is needed, anything input before it just calculates into a sum there).

Based upon the fields input, preliminary results will be yielded in B18 and B30 (green highlight next to these cells), these values then translate to B34:B35 and final result of the larger of the two generates in B37. I do not want a value to register in B37 in red until both B34/35 have a value registered. Text should remain white until both fields have an entry.

Help please!

I am not sure you need a conditional format

in b37 =IF(AND(B15<>"",B16<>"",B28<>""),MAX(B34,B35),"")

I'm not sure I need conditional formatting either however even if I adjust your formula to be (B18 is really what becomes important, 16 could potentially be blank or there could be additional deposit lines added after it)

=IF(AND(B18<>"",B28<>""),MAX(B34,B35),"")

Not having much luck getting this to register a result, it registers b34 in b36 but as soon as b35 has content, b37 becomes blank. I want this to remain blank if either B34 or B35 are blank.

=if(and(b18<>0,b28<>"",b22<>""),max(b34,b35),"")

Thank you JeteMC that seemed to do the trick, sorry davsth I'm still having some trouble with that formula working but I appreciate both responses!
