MultiConditional Formatting or MultiFormula?

I'm a newbie to the forum. I learned Excel by the OJT and "Stumble" methods. I am starting to wish I had used the forum sooner. I don't know the most efficient(easiest with least amount of formulas/columns) way to do the following:

H has imputted data
J has imputted data
K needs to show either H or J data depending on which is less but only if H is greater than 0

Example (I am trying make sure I can understand what I'm doing not implying you don't understand.)
H8 has value $5000.00
J8 has value $1000.00
K8 would be J8 "$1000.00"
H9 has value $0.00
J9 has value $300.00
K9 would be $0.00
H10 has value $500.00
J10 has value $750.00
K10 would be $500.00

Thank you for responding so quickly! I can see how this formula would work. I kept trying to make "IF" work.

OK now for the complicated part of this same spreadsheet.


Like before
H has imputted data
J has imputted data
K needs to show either H or J data depending on which is less but only if H is greater than 0
L now needs to show the value of H minus K unless H is 0.
Examples:
H14: 630
J14: 210
K14: =MIN(H8,J8)or in this case 210
L14: 420

H14: 0
J14: 210
K14: =MIN(H8,J8)or in this case 0
L14: 0

That value would be 0.
