The Result of Adding the Calculation Values of Two Dropdowns is Not Being Shown a the Calculation Field

I am trying to set up a calculation were we can have selection of road race and or TT

I have different option as below and I cant get it go give me a total to be paid

Road race

Option A = R0.00

Option B = R90.00

Option C = R 70.00

Option D = R90.00

Option E = R 100.00

Option F = R120.00

should they ride just the road race then in total due we would need and amount of eg R100.00 (which is option E ) how every if they ride the TT then the value would be

Road race Option E + TT option E = R 100.00 +R100.00 = R200.00 total due

for the life of me I cant get this correct would you be able to help me with this

Sure, no problem.

Assuming I understand the desired functionality, your jotform has lots of unnecessary conditions. It actually needs just one. The expression in the condition's calculation box should be prepended with an R as shown here:

(Also note that the Show empty decimal places box in the Advanced Options has been checked)

The next step would be to insert calculation values into the properties of the Road Race Details and TT Details fields:

After doing the above, your form should work like this clone. Please feel free to clone it in turn to inspect it. If anything is not clear please inform us.
